I watched this tonight after not seeing it for about 15 years. Robin Williams' performance seems even more poignant now. It's a lovely film.
It's amazing to think that Ben Affleck and Matt Damon wrote the script when they were in their early 20s. It was also interesting to see Casey Affleck in a small role. I don't think I paid any attention to him when I saw it first time around but he's very funny in it.
I'd recommend a rewatch to anybody who hasn't seen it recently.
