The main problem with the film is that it feels like three movies in one. You have the Claire/Owen storyline then there is the original trio’s storyline with the return of Dodgson and then the meshing of the two. This means that it feels like they are throwing a lot at the wall to see what sticks. Dodgson is portrayed as some sort of Steve Jobs type person but feels a bit half hearted despite the best efforts of Campbell Scott. Bryce Dallas Howard and Chris Pratt are ok but after being the lead stars in the previous two films, they do feel like afterthoughts because the return of the trio was more interesting to people like me that wanted to see them back one more time and more Jeff Goldblum that we saw in Fallen Kingdom. Goldblum does feel like he is happy to be there but Sam Neill looks like he wants to be anywhere but in the film. That's a shame but at least Jurassic Park III wouldn't be the final film he would be in. Isabella Sermon doesn't really add anything to the story apart. She comes across as a whiny teenager and was irritating. I don't know how much of it is Serman’s fault but she was not really needed. DeWanda Wise got the short end of the stick. Despite her best efforts she just gets drowned out and even in the action scenes it does feel like she is going through the motions.
It’s not a bad film by any means but it definitely the weakest of the JW trilogy but it's not the worst of the entire franchise. I think that they didn't know how they were going to end the trilogy which is something that they should have thought about when they wrote the first one even if 100% guaranteed that they would make more than one. It’s directed well enough but the overall feel of the film is that it doesn't quite know what it wants to be and everyone is just running around trying not to get eaten by dinosaurs.
