Saw this with Jason this evening. I liked the movie, although it's a little on the violent side. Basic plot is this: Uma Thurman was killed and left for dead by her former compatriots in an elite assassin squad. We don't know why. We don't know why they didn't finish the job (there's a little bit of it explained, but it doesn't make much sense). The whole movie is her rehabbing and then seeking revenge. Somehow, Tarantino makes it work so you don't really care why.
Lots of great visual effects. A swordfight in silhouette. A swordfight in snow. A swordfight on table tops and railings. Lots of spurting blood, which didn't look quite realistic (and probably intentionally so). Hacked off arms, legs, and heads.
And a couple of really creepy hospital orderlies. I'm creepy, but not that creepy.
Better than Jackie Brown, but Reservoir Dogs is still his best because of the sheer tension in the group in that movie.
