"12 Angry Men" (1957)

They shouldn’t be allowed to show you movies this good when you’re only in grade 9 or 10 (as was the case with me; it might have even been earlier, I can’t remember). You’re usually too young to appreciate it, and then you go through a lot of your post-high school years with a bias against it because, ya know, some teacher forced you to watch it and you hated it at the time.

I feel the same way about most books we were forced to read in school.
