I was 16 when Jurassic Park hit cinemas and became a worldwide phenomenon and I think it was the perfect age. The action was hugely entertaining, the science was educating in a sense, though preposterous in some ways. I'll never forget the few months of dinosaur hysteria that the film created. And this was a few years before the internet too, so for many it was an introduction to the giants that once roamed the Earth.
Viewing it now, as an 'adult' (and I use the term loosely!) it's as entertaining as it was back then, if not more so. The ethical discussion around the dinner table, Goldblum's talk of chaos theory, "auto erotica"... was all lost on me as a teen, but now it adds even more to the movie.
For a film that is 17 years old with some of the first new generation CGI effects, it still holds up incredibly well. I give complete credit to Spielberg for creating a timeless family adventure movie that I think I will probably love forever.
