I started to dislike Hollywood fx movies after Who Framed Roger Rabbit. I feel that film was the high mark before story content began to noticeably drop. I didn't feel satisfied anymore with the films that were fantasy-driven.
Terminator 2 disappointed me--and while the FX in Jurassic Park amazed me--the cgi*--the story and characters did not. I was underwhelmed.
There was something feeble to them. Nedry and Ian Malcolm were the most energetic characters, the rest were kind of bland.
I liked the sequels better. The Lost World had Pete Postlethwaite and the third movie had the best overall story. Alan Grant was given much more to do and his character had an arc. The ending was a little cheap.
I haven't bothered watching the sequels beyond clips but while the cgi texturing is better than in the earlier movies--it is terrible in other ways. Poorly choreographed. The opening scene for this latest movie is so poorly designed. You just have random shots of dinosaurs and then a big close up on a sleeping one--then the T-rex appears--there's no build up of suspense--and much of their little fight is happening in close up.
It just does not have any excitement.
The big difference in CGI animation today is that when they did the first 2 JP movies (and Starship Troopers), they used stop motion animators to do it. They employed a mechanical device (it looked like a dinosaur made of Lego with wires on it) that would transfer puppet movements to the digital model. After The Lost World, they switched to hand drawn animators--who did not have the same experience with animal motion--and then they switched again to motion capture. Humans running around on a stage and they transfer that to the digital model---and it just is not going to work since a 6-foot human does not weigh as much as a 30-foot dinosaur would.
On the original Jurassic Park they were conscious of how heavy a big animal would be when moving around--especially since they were also matching it to the animatronic ones.
* I was not amazed by the animatronics in Jurassic Park because it wasn't such an advancement compared to the CGI yet watching the behind the scenes of the T-rex more recently--is much more impressive to me. The movements in the movie were very controlled and muted--but when you see the actual puppet moving around without that rigid control--it is impressive how real it looks.
