First of all, the writing is peppy and the kids are fun- I'd like to try another Spinelli book. This one isn't a recommended read for modern children though because of the inadequate way that race is handled. If you loved this book, you may want to skip the rest of my review below.
Problematic. This book is supposedly about a kid name Maniac Magee but is really just a cringefest of race relations in a segregated town. I wasn't able to catch on to whether or not this book actually takes place during segregation or if it was just one of those towns that is still mostly segregated on the old lines despite the decades that have passed.
This could have been an alright book except for a couple of things. First of all, kids absolutely do see color. Give me a break. Prejudice is a natural human tendency that you ward off in your kids by actually taking the time to teach them not to be bigots. I'm sure there's some naturally outgoing kids who see differences a bit less, but, everybody sees it. Another issue I had with the book was that this kid Maniac Magee is just naturally good at everything despite his poor upbringing in a dysfunctional household. Seriously? So despite a poor home life and poor nutrition he is just automatically the best at everything, even sports he hasn't played before? This is where the book gets a serious 'white savior' complex. Guess what? I've worked around kids that have been raised in households that are dysfunctional, you know that they can't do? Untie a knot that no one else could untie. I promise you, those kids can barely tie their own shoelaces or use scissors to cut out more than basic shapes; they aren't untangling a knot no one else could do.
Can a kid who has grown up like Maniac Magee have a special talent? Sure, what would have been believable is if he was just fast, winning races and stuff. That makes sense, kid's been a runaway for a year with nothing to do but runaround town. That checks out. How would he hit a fastball no one on the team could hit having never touched a baseball bat before? That doesn't make sense.
So, who do I recommend this book to? I could see rereading this if it was a favorite childhood book. I have enjoyed some really cringe-y books in my younger days, I get that. You could read it because you are reading all of the Newbery winners; that's why I read it. Other than that, I don't see too much point in picking this one up. Spinelli's writing style is interesting, but, I think I'll stick to books where he hasn't tried to tackle race.
