Jurassic Parks visual effects still hold up today tbh.
They really nailed using practical and cgi in a perfect mesh, the transitions they used to set it up were perfect.
If they went full on CGI it would look really bad today. These reasons are also why LotR looks better then the Hobbit today.
This is precisely it. The practical version of Azog didn't translate as well on screen, so they remade him in CGI.
Also, nostalgia-vision is a pretty big factor in remembering Jurassic Park. The few CGI scenes that still work really well are because they use monodirectional lighting in dark environments to cover the limitations of the CGI capabilities at the time. Most of the "but it looks so fake" stuff comes from seeing characters with lots of scattered lighting effects in open environments.
Insofar as The Hobbit is concerned, most of their CGI looks near to flawless in a cinema (at least the ones that I've attended), but overall I think that most people aren't aware of CGI vs. Practical effects a large amount of the time, because there is SO MUCH that's done with hybridized work still. Prometheus used a ton of practical and special effects that were blended together, and it's hard to tell when which is what.
I think that too often the anti-CGI VFX sentiment falls into the, "I can't recognize this as a practical effect that I'm familiar with, so it's clearly fake" which isn't the same as the CGI not looking photorealistic.
There is a good reason why the characters from the other movies are not returning because they would be smart not to go near any park where there are prehistoric genetically engineered monsters. It would be fun if they got the original actors to play some fake interviews about Jurassic World with all their characters saying its a bad idea even though the park has been running smoothly so far. Ian Malcolm and Alan Grant would be the most vocal because they had twice the experience of being on an island with dinosaurs.
