That's how I feel, 2 was cheesy IMO. It was a King Kong Rip off (and not even a good one) at best.
3 had a nice frantic feel to the movie, and I think I just like Sam Neil more than Jeff Goldblum in general. (Actually, I think Sam is great and Jeff is a waste of good film...)
I like the fisrt one. In that movie you saw the dinos for the first time, so that made the biggest impression. In part 2 the special effect weren't new anymore and the dinos were not new either.
It seems like the first movie of any series is aways better when it comes to suspense. That best part in the first movie is when the water started shaking on the dash board.
