I loved the Michael Crichton novel, but I personally wasn't a fan of the film.

I thought the visual effects were astounding, Jeff Goldblum & Julianne Moore gave fantastic performances, & the trailer sequence was awesome. However, it completely lacked the heart of the first film.

Spielberg himself admitted that it was a dud and that he only made the sequel to try to recapture the success of the 1st film.
