Having seen this movie in the theaters, and re watched it many times at home, there can be no doubt, that this movie is easily one of the best action movies ever made. I could tell you about how the adult actors in this movie were absolutely perfectly cast for their characters, and how the dinosaurs steal the show, but the real meat and potatoes here is easily Ariana Richards and Joseph Mazzello as Lex and Tim Murphy the grandchildren of the parks founder John Hammond. This is quite possibly the best child acting I've ever seen. The expressions and emotions they were able to convey came off as more realistic and genuine than many adult actors can pull off. When I re-watch this movie, and I frequently do, it's at least in part to amazing job done by these two great actors.
The rest you know, Spielberg, Big name actors, Jump scares, Dinosaurs, munch. munch, munch etc, etc, etc......
