Fabulous film, being a huge Michael Crichton fan i'd read the book before seeing the film and wondered how it would translate to a family orientated blockbuster. Needless to say Spielberg produced a groundbreaking cinematic experience, the first sight of the dinosaurs is still my biggest WOW moment after years of cinema going.
His Lost World book is crap though. I'm glad they changed it.
(Well not about the T-Rex doing his Godzilla impersonation)
But the rest of it.
