Look, I get that it isn’t as high concept as the first film (if you could even call it that), but it’s nice, simple fun. A great romp through and through. Don’t take it seriously, just enjoy the ride.
Every Jurassic Park movie is high concept.
Jurassic Park has a stellar cast of likable and interesting characters, a story that actually has a point, a (mostly) fantastic script, Spielberg’s wonderful direction, etc.
Jurassic Park III has Grant with a cast of boring, annoying characters. The story and script are just plain dumb. It hardly has any redeeming qualities. There are some memorable shots/scenes, but three or four cool visuals can’t save a stupid movie.
I mean, all the JP sequels are crap, so it’s not like Jurassic Park III is alone. The JP sequels are the definition of cash-grab garbage.
