What did I think of it? I thought it was one of the best period pieces I've ever seen. But it got to the point where I was just waiting for somebody, anybody, to slap the heck out of Scarlett O'Hara. She was way too hung up on Ashley Wilkes for her own good and it cost her everything: in the end she's this poor delusioned woman clinging to vague hope that it'll all be somehow better. In a way I can kind of empathize with her though: she didn't want to be alone in this world... but to resolve that she tried to have something that wasn't meant to be hers at all.
Anyway, it's a pretty good movie, even if it's soooooo long. I don't know if I'd ever watch it again but at least now I've cinematically lived up to my southern heritage.
