3.5 rounded up. 
 I loved Mim and the fun folks she encounters on her round trip. I found the adults super annoying and unbelievable, though that's probably due almost entirely to seeing everything through Mim's perspective. But really, Dad, really? You suck. This isn't really a spoiler, but maybe so (view spoiler)[ I kept hoping Kathy would actually turn out to be Mim's mom but Mim had projected another image onto her after finding out she was going to have another kid. Alas! But why is Kathy coming after her and not Dad? And, really, Dad was just having an affair with a Denny's waitress because his depressed wife wasn't clicking with him anymore? Isn't that what happened? So...Mim has to go home and just deal with living with bad examples since her mom needs mental health care? Poor Mim! Note: don't cheat on depressed spouses, jerks. (hide spoiler)] Sorry, so much was so fun and lovely, it's just those parents...
