As much as I LOVED the original Jurassic Park, I still think it fell utterly short on conveying just how extremely dangerous the Raptors were in comparison to the book. There is NO way those kids would have survived the kitchen encounter.
That being said, I myself have fallen into the filmmakers trap of unrealistically allowing human characters to escape a grisly death via dinos for tension and story progression purposes. In my 'fan film' inspired more by the book, I have a pretty high body count, plenty of gore and viscera, action, chases, etc. And the balls to have a child eaten by a Dinosaur (Thank you Jaws era Spielberg!) But the main characters (for the most part) seem to avoid death because the force is simply 'with them.'
It's a long shot, but a darker, R rated remake would be interesting.
I'm with Sam and Sticks. No number 4. Would rather see a different movie with Dinosaurs.
