I'm not sure I've read the American Gods novel in full since 2002 or 3, so a lot of this post is about differences between the comic and the TV series, and it may not be of much interest to those who haven't seen the series.
Maybe comics are a very small world - or maybe the comics that interest me are a very small world. Last month I read collected volumes 1-5 of Hellblazer, issues 1-46, originally published 1988- 91. Neil Gaiman wrote a guest issue, and Glenn Fabry was a noted cover artist for the series. The Neil Gaiman connection here goes without saying, but American Gods: Shadows (2017) has spectacular covers by Fabry - which I didn't know when I decided to read it. A number of them, I'd say, are more interesting art than the Hellblazer covers. (Okay, that's partly because I find it weird when he makes Constantine look like Rik Mayall - but these AG covers are wonderfully detailed works of art.) Not only that, but when I hit the 'Coming to America' mini story about Salim and the Ifrit, I thought, 'this is the best panel art in the whole damn book, whose is it?' It was Fabry, the only set of panels he'd drawn in it. (Another weird little parallel with Hellblazer was the way the vertical scar over Wednesday's eye is the same as that on Simon Bisley's illustrations of Constantine for the late-series covers of the late 00s and early 2010s. Maybe it's just an easy way to draw a character with a scarred eye?)
The main art, by Scott Hampton, did the job and was basically unobjectionable. Though I do like something a bit more detailed or characterful. The very best thing he drew IMO was winter trees in the background…
Although some illustrations invoke the TV series, for the most part it's obvious this comic is adapted from a novel. There are a lot of panels where the descriptions aren't the sort where every word counts and - even if they've been trimmed a bit - evoke prose writing that expects to go on for paragraphs.
I'd love to know more about the timing and relationship between the comic and the TV series. Some characters in the comic look so much like the actors that they have to have been based on the TV versions, especially the Ifrit. Many others look like totally different people, but occasionally take on facial expressions just like their actors, as Wednesday and Salim each did once or twice. Where character appearances differed between comic and TV, usually the comic version made more sense - even whilst the actors are excellent in their roles. Scraggy comics Mad Sweeney looks like my old idea of the character from the novel - much like the Rainbow Riches leprechaun - and fittingly dressed like William H. Macy in Shameless USA; less telegenic than the Conor McGregor lookalike he is on TV. Ian McShane inhabits the role of Wednesday perfectly (plus he seems to evoke Gaiman as RL presiding spirit), and as a result the comics incarnation, who looks different, doesn't seem to have anything like as much charisma. But at the same time, if you'd heard without further info that McShane was playing a modern version of an ancient god, you'd probably assume from his looks that it would be Greek or Roman; this taller, red-headed Wednesday is more like the standard fictional and artistic idea of a Norse god. (Albeit it's Thor who was nicknamed Redbeard in sagas.) The comics gods are mostly older in appearance than their TV counterparts, which makes sense in their stories. I think it gives the show more vibrancy to have them a variety of ages - I'm not sure if this is ageism on my part but. In particular Mr. Nancy in the TV series, with his BLM-relevant speeches, it seemed fitting to make younger. Perhaps the biggest difference is in minor characters: for example, Bilquis' first conquest(?) is much better looking in the comic than on TV.
The biggest difference between the comic & novel, and the TV show, is in Laura's story (and her team-up with the longer-lived TV Mad Sweeney and the younger TV Salim, the latter whom I find very likeable). In the novel, I found Laura & Shadow boring. I did too the first time I watched the TV series (only 4 episodes). But then when I watched it again, and the whole series and the next, I thought she was a great character, anything but boring. Laura in the comic was a travel agent and wears a sensible skirt suit, and basically seems (so far) responsible except for her affair. On TV she was, when alive, a small-time bad girl who never managed to get her life to match her ambitions. As a zombie, she's been forced to exchange sex appeal for brute strength; she grapples implicitly with this, loving the strength that means she can now back up her confrontational nature, but feeling lost that she can't flirt effectively or be physically desirable any longer. There's something epic about the force of her personality, even more so because it's made tragic by her limited lifespan as a zombie. And, even more so after the episode in the second series where 18th century hustler Essie McGowan (Essie Tregowan in the comic and novel) is played by the same actress as Laura, Laura seems like a frustrated trickster goddess in waiting - a type of woman who's existed for all of history, making her fortune via seduction, sneakiness and petty crime because that was usually the only possibility if not born rich, and it required a lot of guts and ability to ignore social norms - and for whom there should have been a sacred avatar. Except that she's of a type that's rarely been respected unless they made it all the way up to Empress or similar. So yeah, it's a bit flat to come back to this more normal sensible version of Laura.
Racial ambiguity is a significant part of Shadow's life story and appearance in the novel, and it's easier to drawn that in a comic than it is to cast in someone who is *also* a good actor for the role in other respects. As the comic follows the 2001 novel, it has less to say about race, whilst the TV series has made itself more contemporary by making present in the directing, and subtly in the script, questions like "How is it for Shadow being around all these old white gods?" There seems to be an almost constant racial tension in the show, and sometimes an overt sense of menace mingled with old white people's clumsiness, as between Czernobog and Shadow. Yet, for some reason I have never been able to fathom, Shadow in the TV series, although it's emphasised he's an intelligent, well-read guy, is weirdly slow to suspect/understand who the gods are. (IMO even if he's sceptical, he would twig their identities soon enough, he might just think it was a dream or hallucination.) Shadow in the comic is quicker on the uptake about this - which is good.
Sam Tallbear is another character who's been altered somewhat for the TV series to make her a stronger and more contemporary representation - and her story about the Norse gods Coming to America is used at the start of the TV series, replacing the one about Vikings killing a Skraeling (Indian). The TV series (despite the very stupid decision to fire Orlando Jones) projects a sense of contemporary centre-left social responsibility when set alongside the comic & novel, written at a time when pop culture was less overtly political - a sense of responsibility also evident in the decision not to include fringe historical theories about e.g. the Ainu, or Egyptians, the Welsh or Irish, or West Africans, or the Chinese reaching America before Columbus. (Although they've still left in the lines about America being a bad land for gods, which have never made a great deal of sense - and were among the first flaws I became aware of in the novel, and which demoted it from my all-time favourites.) The comic is uneven about updating smaller details for the present: Shadow has an e-ticket for the plane, and a vision is described as 'streaming images' but a bankrupt-stock warehouse still contains Ninja Turtle toys and Bill Clinton watches, as it would have in 2001. (Did the writer think it would be too depressing for the audience to change the latter to Obama memorabilia?)
And sometimes I'm just confused: the current version of the novel ('author's preferred edition') totally misses out the scene shown in the TV series where Audrey tries to have sex with Shadow after the funerals. I *think* that in the original novel they actually did - that scene made an impression on me when I was younger - but that's not easy to check now.
Some reviews from readers who read the comic soon after the novel suggest it may get repetitive to read both in a short space of time. However, for someone like me, who wouldn't mind a refresher on the novel, but doesn't really want to do 600 pages worth of re-reading, it makes sense. For all that I've mentioned a few criticisms here, I enjoyed this adaptation and found it interesting to see how this story worked in another medium.
