No action on the island? Are we talking about the same film?
I can't understand why people generally don't like the 2nd one. It was the best! Witty dialogue, interesting and probably quite accurate portrayal of dinosaurs, tension - the trailer scene is a classic, and the arrival of the cargo ship in San Diego! And Jeff Goldblum was given a decent role whereas he was completely wasted in the first one. The third one was dire, complete with inaccurate portrayal of dinosaurs (the Spinosaur).
