Good (sorry if I put some spoilers here)

Rating: 8/10 (30 May 2000)

I really don't understand these bad reviews. There are two bad things I could say about the movie.
1. O.K., it's true, almost all the scenes are known from the first part or from another movie. 2. O.K., the story is quite stupid.
BUT
1. It was fun that all these scenes were better/faster/bigger (more T-Rexes, more types of dinos, bigger car falling etc...) than in the first one. This is a basic rule of sequels, right? Of course, there is another way of moviemaking - look at Spielberg's Indiana Jones sequels or his production, the Back to the Future Series, or friend George Lucas's SW Ep.5 and 6. They all did what the best sequels do - doing something completely different on a same high level just with not going too far from the original. JP's sequle tried the other way, I think quite well. Because of the same storyline, you could have expected the end of the film when the helicopter took our heroes - and then you had quite much more.
2. The story is not so clever - so what? Even the first episode wasn't too clever, either. But we liked it because it was a revolution in special effects. Was it a really clever, well developed, first class movie? I didn't think so altough I liked Spielberg's style. But almost everybody remembers the first film was amazing - just they don't remember why it was a real enjoyment.
But please, it's an entertaining spectacular movie, it doesn't want you to think, only to enjoy it. And it has lots of fun in it. Think of the cut between the first scene and Goldblum's face. Think of the back window of the bus. That was an amazing scene, can you remember the lines appearing at the fingers of Julianne Moore? Or think of when the boat appeared. On the same summer we had another boat landing (Speed2), but that was soo long and boring (I think it took some minutes). In Lost World it was very fast and very entertaining.
And the special effect were really awesome.
One more thing. You didn't like the script? You can see when the T-Rex eats the screenwriter...
