I quite liked it. I went in expecting flashiness and hot chicks fighting, and in that he did not disappoint. But I also felt it had depth, with the flashbacks and the thing she was searching for. I like stories that reveal things bit by bit, and that expect you to keep up (see e.g. Memento). I felt Tarantino did a great job with that, while indulging himself with the things he (and a lot of Americans) likes-- trashy, bright-colored things blowing up real good.
