There's good popcorn movie like RAIDERS and JAWS, because of their stories. Then there's JURASSIC.
Given a choice between a story about a fish that not only goes out of its way to hunt a specific boat, but also willingly and repeatedly uses its most sensitive body part as a battering tool against wood, and a story about dinosaurs escaping from their theme park... I'll go with the latter, thanks.
If we're going to get reductive about plausibility, I think a movie about a shark that eats people and attacks a boat is more plausible than anything you'll find in Jurassic Park
. Think about it; a corporation is able to keep secret a group of scientists cloning hundreds
of dinosaurs from partial DNA samples and the construction of a massive, hugely expensive theme park -- both of which appear to have been accomplished in a relatively short period of time.
