Robocop was the first R-rated movie I ever saw. My Mom was quite overly-protective so I didn't see that many, well, COOL movies until I was about 12 or so. My parents would "preview" films they felt were iffy and often they maintained a firm "NO" as the answer. I actually think taking the time to watch films they weren't sure their kids should watch was great parenting (I plan to do the same thing) but they were WAY too strict with it. Harmless stuff like Batman and the f*cking INDIANA JONES movies were considered too violent or scary or whatever.
Anyway my Dad was a little more slack about this stuff. My Mom was out-of-town for a few weeks and this was when the Robocop TV show was on and we all thought it was pretty cool. So my Dad rented it for us on a night that he had a class or something. Anyway I was baby-sitting. Five minutes into the film ED-209 rips that executive's body apart with bullets and my youngest brother who wasn't even ten yet practically goes into shock. We had NEVER seen a film like that before. Most films we had seen didn't even kill off bad guys let alone kill ALL of them off with blood flying everywhere, not to mention a guy getting covered in toxic waste and then EXPLODING into guts after getting hit by a car. This film also had REAL swearing. Before that a bad word in a movie for me was "damn", "ass" and "sh!t". In this film everyone said "f*ck" without batting an eye.
For years my brothers actually didn't like the film because it was so violent. As kids we didn't get the obvious satire. Later I saw it again and raved about how great it was and only recently when they caught bits of it on TV did my brothers finally start to consider it a good movie. I hate the sequels but the first film is awesome.
It had the unfortunate timing of being our first big shocking R-rated movie so it doesn't get the same respect in my house as Terminator or Predator do. Too bad. The 80's was the decade of killer action movies. Lots of crap too or course but the good ones are amazing.
