Not so much U shaped as you say. 19 5star reviews, only 2 1star reviews and no other reviews as of right now. Kinda seems like the author had his buddies review it on amazon at this point. But this could be a good book; I didn't read Flash Boys, but if I do or did, I would want to read something like this as well.
