I watched the movie on a plane, I just generally like stories about coming of age, kind of like Glee with "awkward" characters, because I was one too. Still am.
Then the movie showed a couple of gay characters, and I was interested in that too.
Then the CSA and I could totally relate, even though my abuse was different. It helped explained the wallflower personality as something probably beyond standard shyness, and the mental-health issues, which I have also had.
I liked the ending too, I won't say more. I recommend it.
