I liked this quite a bit. I like Lemire's work, generally, though I like his earlier, edgier Essex County and Sweet Tooth stuff, with his own rough, sketchy drawing, but I liked the fairy tale romance Trillium, and most times (unless it is his superhero writing, which I dislike), I am inclined to like his work. What seems central to much of Lemire's work is the abandonment of the son by the father, or parents, but usually the father, and the search for reuniting them. Empathy, vulnerability, a certain melancholy sweetness are all central descriptors of his work, so this story fits that mold. As others will tell you, this is a science fiction story, a space story with debts to Star Wars, to Spielberg's AI, to Asimov. It's a genre, so I have no problems with it's being resonant of other stories. Vaughn's Saga also is a tribute to Spielberg and Lucas, trying to get back that magic in the still cynical post-superhero comics era, so even though I am not a particular Lucas-Spielberg geek, I appreciate the moves.
The main character is TIM-21, a boy companion robot who has been asleep on a moon for about ten years, wakes up, repairs a little barky dog bot, and begins tinkering with a computer, so people from other worlds become aware that this bot is alive, and for some reason can solve a problem they are having, a problem that doesn't really interest me. I had a hard time getting into the intergalactic crisis aspect of the book, which is why it is something like a 3 to 3.5 for me. It feels pretty generic in a lot of ways, I suppose. The inventor of Tim-21 is a nerdy loser fraud of a scientist, so even he is a kind of stereotype. There's a large Driller bot (from a mining company) who always yells he is a Killer…. ugh. It's all meant to be cute and Lucas-like….though there is one super violent moment in it that moves it out of ET category, that's for sure. Happens to the Inventor guy, so be warned.
Still, I liked it quite a bit. I like Tim-21, which is what Lemire cares about. It has this Star Wars-Luke innocence to it. That Lost Boy, aw, let's give him a hug quality. It works pretty well, though! And Nguyen's art is good, a kind of cross between generic superhero art and Lemire's scratchy art, so it's a good compromise as I see it. And Nguyen finally is a more accessible artist than Lemire, so there's that.
