The first Jurassic Park movie is all time one of the greatest films ever made with the special effects still holding up to this day. The 2nd film was still very enjoyable in my opinion but it was just a cookie cutter sequel not bad, not good. The 3rd film wasn’t great at all. But compared to the rest of the series the 3rd film is basically the godfather.
As another personal pick the 1st blade movie is a hood classic good. The other 2 not so much.
I felt bad for Lost World, because Crighton went out of his way to write a novel that was a sequel to the first movie, not the first book, and then Spielberg just basically ignored it like it never happened.
I wanted to not see the chameleon dinosaurs, damn it!
The upside is that the movie is good and the book is great and one won’t spoil the other.
