Jurassic Park was my life when I first saw it. If I had to construct a Top 10 Films of ALL TIME list than Jurassic Park would be in the top 5 simply from the memory that I have of it.
It blew my 12 year old mind, I had never seen anything like that before and was just in awe of the special effects and the adventure of it all. Every time I watched it I would always imagine myself 'in the film' as a 3rd grandchild of Richard Attenborough, getting into scrapes, and being chased by dinosaurs. It literally was my world.
When everyone else, at 12 years old, starting snogging girls behind the bike sheds, smoking a cigarette for the first time and genuinely just 'being cool', I was too busy setting up the 'Jurassic Park Club' that I held in the computer room at lunch times. There were only 2 members, myself and this sweaty, smelly girl that use to shave her eyebrows off...it only lasted a couple of weeks
But yes, Jurassic Park is a contender for best film ever.
