Jurrasic park was very much an impressive and great movie for the same reason the original Avatar was. The plot was decent or okay but the graphics and visuals blew everything at the time out of the water with such a magnitude of difference that the sparkle in your eyes stayed through the movie. Sure, looking back now, now that we have great CGI and 4K OLED screens, it may not be as impressive. But think of Legend of Zelda, Ocarina of time. Also basic and nothing visually amazing...by today's standards point but it was an insane feat for the time.
We now judge Jurassic park by the quality of it's story much more now than we are amazed by impressive dinosaur like we were back then. So of course it's gonna look mid at best
Anyway, that's my take on it at least.
