From one of my favorite Web site, a biologist who reviews SF films.

In her latest installment, she takes on the original Jurassic Park:

I remember when it premiered even the stuffy, elitist NPR reviewer was so overcome by
seeing the dinosaurs on the big screen seeming so real that he didn’t even bother to seriously
critique JP.

I was not as enchanted by the next two JP films (hey, let's give them MORE dinosaurs! They
won't need a real plot or likable characters!), though the scene in JP3 where the main good
guy is trying to call for help and the little kid is watching Barney was amusing.

They have been threatening to come out with a JP4 for a while now, but the project seems to
be in limbo:

Which, judging by the above average amount of cinematic junk forced on us this summer,
may be a good thing if JP4 doesn't happen.
