But if u haven't u should see The Shawshank Redemption, in my opinion one of the best movies there is. And almost anyone can watch it, from 7 year old children to their grandparents.
If u like horror movies, then go for the ones based on Stephen Kings books, I saw Rose Red, and I had to sleep with the lights one for the next few nights. And the night I watched it I didn't sleep at all.
Also The Silence of The Lambs, Hannibal and Red Dragon.
