The TLW raptors weren't bad at all, but they had a certain feeling of... scripteness to them? Like, when they appeared, it felt like a time that they would and should. Jurassic Park's were just terrifying, full of animalistic unpredictability. They always showed up at the worst time and you never saw it coming; they made the jungle and by extension, the facilities, feel like the Nostromo -- where every turn was a dark one and you always had a sense of being hunted.
One of my favorite moments is one you don't even see, just Muldoon telling Ellie (and the audience) what he sees... and we know to trust him because he's a seasoned hunter and tracker. So what does that mean when he's bested by the creatures? Nothing good is to come.
Jurassic Park 3's raptors? Abomination-tier. Passive, felt highly scripted, and existed only to feed a shitty side-plot. Let's hope Jurassic Park IV does them justice.
