I just saw it. I liked it. I liked part 1 more because "less is more."
It was definitely a 2.5 hour infomercial. There are scenes that could've been left on the cutting room floor. There were attempts at funny that weren't as funny as the actress laughter symbolized.
Scheduling conflicts made my friends and me have to see the movie separately. Same day, different theaters. We'll have to see it together to get the group effect.
I will buy the dvd, but it probably won't be all worn and overwatched like my part 1 dvd. I also probably won't stalk it on HBO OnDemand like I stalk part 1.
