SPOILERS
I'm with you, SmartAlec.
I was about 19 when the first one came out, so less nostalgic, but the first film really was good. They got progressively worse but this was the pits.
Nothing really new done with the dinosaurs, a lot of plot holes and inconsistencies (how did they get Mossasaur DNA if they obtained it via mosquitos in amber, given Mossasaurs were sea-dwelling reptiles and unlikely to get sucked by a mozzie?), the humans were 2D and boooring, the kids were a) really unappealing, b) bizarrely RetroBoy (the younger one, that was. 70's hair, clothes, v v retro bedroom with the sorts of cute vintage toys, even the dinosaur models, that are chosen for nurseries by parents who think they look cute). There was zero attraction/chemistry between the protagonists, and not a sniff of a real palaeontologist.
No decent female characters. No truly funny dialogue. No Jeff Goldblum.
If they'd developed the 'this is what jerks human beings are - they take a cool science thing like cloning dinosaurs and turn it into Disneyworld' angle a little more, I'd have respected it a whole lot more.
However, my dinosaur-obsessed 7 yo lapped it up, cried a tiny bit when the poor raptors got fried, and generally loved it all.
