I know it gets a bad rap, but it is a cult classic in my book. The most perfect symmetry of science fiction and body horror since Alien(s). Add on top of that a fantastic cast, a mildly campy vibe, and it somehow manages to hold up well even today in my opinion. Even though it scared the fuck out of me as a kid, I have a weird nostalgia for it now.
All of the issues with Event Horizon are because of the studio screwing up the story. And the footage of the good version of the movie was lost on the cutting room floor, so we'll never see it.
Its such a good premise and so well executed that its still good despite its story & pacing issues. One of the best moments of my life was showing it to my Warhammer 40k loving friend for the first time. It blew his mind.
There was so much I never knew about the production of the movie until the guys at Red Letter Media did a Re:View about it. I was kinda bummed that Mike and Jay didn't like the movie, but it was cool to learn the history, warts and all.
I keep holding out hope that someday it might be remade or perhaps there could be a sequel from a competent team that enjoyed the first movie. I am generally against remake or reboot culture, but Event Horizon just always seemed like a perfect candidate for it to me.
Watching it solo in the middle of the night thinking it was just a regular sci-fi movie is what fucked me up. I was like "cool! spaceships! warp drives!" and then had my world fucking rocked.
