The Green Mile was pretty damn good. It's very much along the lines of Shawshank, but with a bit more supernatural elements. Some of it is pretty fucked up, too.

Shawshank is a bit overrated. It was number 1 on imdb's top 250 for ages, but a lot of that was due to users trying to rig those lists. It's an okay movie, but nowhere near the greatest. I happen to think Escape from Alcatraz is a better and more eerie prison movie. Still, it's interesting that Tim Robbins will be in season 2 of Castle Rock.
