The Shawshank Redemption is NOT APPROPRIATE for school!!! I didn't even think about it as I was reading the sub notes, but guess what, there is sex, swearing, F Bombs, talk of sex, more talk of sex, rape, beatings, and yeah MORE. I always watched it more for the story, but all of the details STAND OUT when watching it with a room of teenagers. The kids seemed to know they were going to watch it, so they must have discussed it ahead of time, maybe got permission slips? Although some of the kids seemed really uncomfortable.
It's not like they were reading the book. I haven't seen Stephen King on the approved high school reading list yet. It seems like a different movie could have been picked.
