Perks of Being a Wallflower

It was an engaging book. Written in letter format ( just from the protagonist, no replies) and detailing the trials and tribulations one of his teenage years... Don't get me wrong, the character has got some legit baggage.
I didn't really like the end though. I both expected the big reveal and didn't really like how it was pulled off.
Overall though, I thought that it was a worthwhile read.
I'm curious how they translated it to the big screen... I wonder if it's on netflix.
