I don't really mind JP3, as far as films go it's alright, I guess the problem is that it's part of a trilogy (currently) that includes to superior films and that just makes it look bad.
Iguess it's like being the manager of car showroom but your older borther and sister are astronauts. The manager job is great but astronauts are frickin' awesome.
I'm half tempted to edit this post to remove the above analogy as it may just be the dumbest thing I ever posted. Meh
But yeah, JP3 I like. What I think let's it down is that it really is just an action film with dinosaurs, the first 2 had themes running through them
You could say that JP1 questions the whole ethics of genetics and mankind meddling with what some would call 'playng god' and then JP2 is pretty much an enviromentalist statement.
At least that's how I look at them.
