I found Kill Bill 1 to be entirely more entertaining. Being an avid Tarantino fan I had expected alot from both Kill Bills and I was sadly disappointed with the second one.
For those who say the dialogue was pure genius, I'd have to disagree. Some of it was well-placed and funny (Reminds me of Be just saying "Bitch." to Elle after she finds out about [not spoiling]'s death) but for the most part it was boring and drawn-out (the tranquilizer scene at the end comes to mind). Don't get me wrong, the acting and the characters were top-notch in the way they were played, but the movie itself was far too drawn-out. It was the polar opposite of Kill Bill 1. But hey, maybe thats what Tarantino had in mind. It just wasn't what I thought it was going to be, and I guess that's what ruined it for me (the environment couldn't have helped either; I work for a movie theatre and I saw the sneak preview of it the night before- it was very Mystery Science Theatre-esque).
As a side note, the Punisher was indeed a badass movie. Travolta plays a villain very well, and whoever it is that played the Punisher was absolutely perfect for the role.
