I probably won't see Fallen Kingdom in theaters because of the Fifa World Cup, so I'll revisit this later.
Let's just toss out JP3 right away. It sucked and isn't in the conversation. The only decent thing it had was Sam Neill. He deserved far more than the crap that surrounded him.
That leaves the other two. The Lost World had the best character of any of these films outside of the first one, Roland the game hunter. He was great and when he's on screen the movie is so much better for it. The Lost World is also more substantive. It is actually about something. On the other hand, the film isn't executed all that well, the basic plot was done much better in King Kong (both the original and the Peter Jackson version), and it also had some truly annoying characters (Harding, Vince Vaughn, Malcolm's daughter) that really detract from it. While there is nothing wrong with cheering for the cool villains, I do have trouble when I find myself sympathizing more with them over the heroes and TLW I did.
Jurassic World was less serious than TLW, but as a non-stop thrill ride it worked. If the T. rex coming out at the end ready to kick some ass and save the day doesn't get your blood pumping, you have no soul. It did make the mistake of killing the best character (Masrani the owner) halfway through the movie and it is certainly a lot goofier, but I ultimately enjoy watching it more than I do TLW.
