The first Jurassic Park movie is all time one of the greatest films ever made with the special effects still holding up to this day. The 2nd film was still very enjoyable in my opinion but it was just a cookie cutter sequel not bad, not good. The 3rd film wasn’t great at all. But compared to the rest of the series the 3rd film is basically the godfather.
As another personal pick the 1st blade movie is a hood classic good. The other 2 not so much.
I actually thought 4 was better than 2 and 3. Not that 4 was very good, but I thought 2 and 3 suffered from an attempt to, “trilogize,” the series and make it a grand epic. It was clear by the end of the third movie that they didn’t know where they were going with all of the plot threads they’d set up like Calypso, the Brethren Court, the Jack/Elizabeth/Will love triangle they were hinting at…just way to many ideas and very little payoff. At least 4 told a coherent story in one movie, even if it wasn’t a very good story.
