I saw it and despite having to sit in the second row because the theater was packed, I thoroughly enjoyed it. I'm not that big a fan of Tarantino (Reservoir Dogs is the only other movie I've actually enjoyed) but he did a pretty good job on this.

My only complaint would be that the climax dragged on longer than necessary. The violence didn't need to last as long as it did and the movie could've focused elsewhere during that time.
