Pretty much every movie based on a Crichton novel except the first Jurassic Park and the original 1971 adaptation of The Andromeda Strain. Every other one has been awful (including The Lost World which is so far from the book it shouldn't even get to be called "based on").
Edit: After sleeping on it, I don't know if the movie adaptations are objectively awful or if I was just unimpressed because I read the novel first for all of them.
I agree it is acceptable, I don't often miss an opportunity for a marathon- it just isn't really true to the book, it's more like bits of the book are scattered throughout the movies.
And I'm really upset that Hammond didn't get eaten cause that would have been awesome.
The novel was great. The movie....eh, not so much (IMO, anyway). Not even the combined powers of Dustin Hoffman, Samuel L Jackson, and Queen Latifah could really make it work for me. There's just too much subtlety in the book that didn't make it to the screen.
