Easy on the okie jokes! ;P
The reason I liked it so much, well, it just had that something special... that magic about it. Also, it was really funny, and the humor wasn't contrived like it was in JP2... but (I thought) it was so appropriate. Also, graphics were obviously awesome. Sure the plot isn't always the best but it really was a great movie. Could have been because it was free though (wife won the tickets on 106.9 radio or something, so everyone in there was pretty happy about that). Not to mention it was jam packed and everyone was roudy and excited. All of the DJ's kinda got everyone all in a frenzy before it started.
Seriously though, I really liked part 1, hated part 2 and loved part 3.
