The first Jurassic Park was by far the best. It came out at just the right time and was, as I recall it, instrumental in reinvigorating the interest in Dinosaurs. The experts at the time were using Stop-Motion or the newer Go-Motion and CGI was still a new technology.
There were actually going to use the Motion systems till Spielberg saw some test footage of a CGI T-Rex and then decided to use that instead. They still kept the Motion experts as they built a metal T-Rex model that they could manipulate and convert those movements into the CGI rig for the animation process that was used in the final movie.
I love Jurassic Park and dig it out a few times a year. The Lost World was watchable but a defo drop in quality but I didn't care for #3.
Jurassic World was ok but the quality again dropped after the first one.

Did you know that in the 1980s movie PREDATOR the titular character was not originally portrayed by Kevin Peter Hall. It was in fact Jean-Claude Van Damme donning a much more insect inspired full body suit before he left the production which then led to the recasting and redesigning of the famous hunter.
