I liked 1. I didn't care for the kids that much either, but Dr. Grant and some of the others shared enough scenes with them to make them tolerable. Wayne Knight's death is a classic and who can forget the old "Mr. Arnold? Oh thank goodness-- AAARGH!!". I can't count the times I've made fun of that one in some way.
When the girl started doing damn gymnastics in 2, I knew it was over. That and the fact that I didn't think Mr. Malcolm was into teh chocolate. There were some good parts, just not enough of them.
3 was somewhat enjoyable, though I was somewhat annoyed by the kid. And that duder who stole the egg reminded me of Strafe. I'll also remember 3 because Merla and I saw it on opening day. We were running late and it was soooo crowded in the theater. The guy was like "It's nearly full, are you sure?" and kept wasting our time with those sort of questions. The minute I paid and my tickets popped up, I snatched them and left.
I have no idea what to think of 4. Does it still involve intelligent dinosaurs or was that just a baseless rumor?
