Let's see...great story, great dialogue, great acting, great visuals, great special effects, great music...add it all up and you get an unbelievably great movie experience. Without a doubt the movie of the year so far.
I had high hopes - good director, and I remember liking the first movie - but I thought this one was just okay. Most of the humor felt forced, most of the regular dialogue felt stiff, and most of the fight scenes felt a little too over-the-top. Visually, it was great, although there were a couple scenes where you could tell they were using CGI on top of a blue-screen.
Oh, also, Selma Blair is just not a good actress. There's really not much more to say about that.
Anyway, it's decent enough, I guess. If you liked the first one, the odds are you will like the second one.
