Picked this title up because I thought it was about a mystery-solving octopus. I love octopuses. They happen to be my favorite water animal, and I just finished reading The Soul of an Octopus by Sy Montgomery (which is a far better read if you're into octopuses). Remarkably Bright Creatures is not about a mystery-solving octopus. The octopus knows things that the characters in the book don't know, and makes feeble attempts intermittently throughout the story to clue the characters in. However, the "mystery" could've easily been solved without the octopus. In fact, readers who pay just partial (maybe 2/5ths) attention will be able to figure it all out halfway through the novel, then have to plod their way through the rest, waiting for the characters to catch up.
All of this might have been forgivable had these characters' lives included any drama of moderate interest. If I told you this book was about a 70-year-old cleaning lady (Tova), her knitting friends, and a 30-year-old fuck-up (Cameron) who can't hold a job, well ... that's what it's about, and it's as interesting as it sounds. True, Cameron is supposedly a genius, and this could've added an interesting element to the story. Unfortunately, he doesn't act like one, nor does his alleged intelligence serve any purpose in the plot. At all. Maybe two or three times he will spew some random factoid about something or other, but it's not anything that helps anybody. It just happens.
There is a moment when a cat shows up (named Cat), but again, it doesn't do anything important other than cat things. Not sure why it was put in the story at all other than that author Shelby Van Pelt happens to be a cat person. When it arrived at Tova's front door, the narrative lingered on it and Tova's reaction to it so intensely that I felt certain the cat was going to play a major role. But it's really just there, being a cat. Not sure how much I can fault this, though, seeing as every cat I have ever met acts just like Cat in this novel. It's a believable cat.
The ending was a pile of ass. Not going to spoil it, but when I said that any slightly attentive reader could figure the whole thing out, that's not entirely true. It didn't end the way I expected it to, but it wasn't like "Wow! That was a crazy twist I didn't see coming!" It was more like, "Ah, I get it. This is what's going to happen, and that's going be quite nice because of the themes of home and family that are being developed ... oh wait. What? Damn. Why the fuck are they doing this instead? What? This makes zero sense and is not satisfying at all! I'm not satisfied! And there's that cat doing cat things again!"
So, in sum, main character's life is boring. She cleans at her job, cleans at home, sometimes goes grocery shopping and hangs with her knitting group who are equally boring. Cameron is that guy nobody wants to hang around with because he's 30 years old and acts like he's 19 with his freeloading whininess. Marcellus (the octopus) is a bit more interesting simply because he's an octopus, but his parts in the novel are way too few and way too short. He's more like a wise, old narrator watching the non-action and coming in every twenty pages or so to comment for a page, but he doesn't say anything that the reader doesn't already know.
In fact, as a reader, I identified with Marcellus more than any other character because reading this novel was like being an octopus in a tank, languidly observing the boring-ass lives of people through a glass and wishing I were out swimming in the ocean where there can be some hope of excitement.
