Steven Spielberg has always been fascinated with the wonders of childhood, the perils of technology and the gulf between reality and fantasy. Once again, in the summer mega-movie Jurassic Park (B+), he opens up a mysterious childhood treasure chest to unleash the demons within it. In the film he proves most kids have a certain wide-eyed interest in dinosaurs, and adults will exploit such unknowns if given the chance. After Hook, Spielberg is thankfully back to formula form. The story is essentially an island theme park of dinosaurs re-created in modern day like a high-end zoo — and that turns out to be a terribly bad idea. The effects are great, many sequences highly suspenseful and the characters are almost all dull and underdeveloped (especially Sam Neill, Laura Dern and Richard Attenborough). Jeff Goldblum thankfully provides a bit of comic relief.  This is a theme park ride and a sequel franchise unspooling before your eyes.
