It's been a million years for me too, I just remember I liked it. I also liked What Dreams May Come and Awakenings. (I liked Good Will Hunting too but somehow don't think of it as a Robin Williams film, probably because he wasn't the lead.) (ponders) Those and Mrs Doubtfire are all of his films I've seen, but those are most of them I think.
We've lost some great ones this year, haven't we?
