Bicycle Thieves - worth seeing once but it's so sad that I doubt I'll ever rewatch it. I prefer Umberto D.
The Graduate - I find it hard to have opinions on this as a movie since it's such a cultural touchstone. I think it's somewhere in the good-to-very good range.
Carrie - I've only seen the ending, which holds up.
Stand by Me - maudlin garbage.
Inception - good, although I wish there were a little less DiCaprio in it. Maybe I just don't know if the plot about his wife really makes sense.
The French Connection - good.
The Usual Suspects - pretty good. I rewatched this recently and, knowing the twist, it's still alright.
