Maybe to just put a bookend on this thread, I did see this on vacation with the family. To give a spoiler-free review:
"Eh."
It wasn't bad bad (as in Transformers or Armageddon)... and if your expectations are low you'll survive. It certainly wasn't great, but a lot of people I know have said they enjoyed it. I'll give some credit where credit is due; the raptor training scenes are less ridiculous as the trailer makes them (based on my experiences with exotic animal handlers). Plus, along the lines with some of the comments in this thread, at one point a character fully acknowledges that these dinosaurs are NOT real dinosuars but guesses made in a lab, something that was more prominent in Chrichton's book, IIRC.
Heard something funny right after it came out:
"A corporate executive, in an attempt to increase profits, creates a questionable mix of past successes in order to satisfy audiences, and when it escapes..."
..... is both a description of the plot, and of how the movie came to be.
