RoboCop is my favorite movie ever. I saw it in a theatre back in 87 (I was seventeen at the time) and at that point it was the single most VIOLENT movie I had ever seen in my life. Naturally, I loved it.
Between the balls-out action, the gore, the black comedy, the sci-fi elements, it was like a really kick-ass comic book come to life.
I've seen it dozens of times since then and I'm generally not a person who watches movies repeatedly. I just never get tired of it.
Didn't mind "RC2" but "RC3" was just... ick. "Lookie kids, RoboCop can FLY! Make sure to tell Mom & Dad to stop at Toys R Us on the way home from the theatre to pickup the All New Robocop Jet Force Action Figure!" -- ugh.
