Well, some chapters of this collection are very closely tied to the Civil War event, while others have almost nothing to do with it, and if you've seen my ratings for other Civil War Marvel books, you can probably guess which ones I enjoyed most. However, I even thought the more CW centered chapters were actually pretty cool, telling events of the core book from a different angle, lending some insight into what else was feeding the circumstances. Also, Reed's motivation for being involved made a hell of a lot more sense than anyone else's. (Asimov FTW)
The highlight of the book is the third chapter, "Many Annoying Things, None of Them French," which sees Ben "The Thing" Grimm on a solo adventure with many French superheroes, (some of them suspiciously familiar) some may find the bizarre cast of characters reminiscent of Edlund's The Tick, but I particularly was fondly reminded of Waid & 'ringo's run on FF.
The final three chapters came from an FF anniversary issue. The main story, with the characters watching a documentary about themselves, seemed a bit weak. I just feel like this is what superhero comics always do at milestones, yet it was effective nonetheless, giving me the intended fuzzy feelings. The other two were fun little tributes, but "A Day at the Races" featured some seriously amateur hour art. Don't know what was up with that.
Lastly I just want to say to Dwayne McDuffie. That was not alright for you to go and die on us. Your fans need someone like you, and I can only think of a few that work in your style, and not one who measures up. Not cool leaving us man, not cool.
