Oh man I can't wait for Event Horizon.
DVD Beaver nailed it regarding films you think are "ok" on first viewing but which grow on you afterword.
For me BladeRunner was like that: I had high hopes for R. Scott's next film after Alien, but walked out of BladeRunner feeling I'd just seen the most dazzling visuals I've ever seen coating a rather bland story, told with little passion. But the visuals drew me back again to see it and with the initial "disappointment" already registered and expectations lowered, I began to appreciate more of the movie, until it became (as for many viewers) one of my all time favorite films.
Likewise with Event Horizon: I LOVED the Lovecraftian sensibility of the movie and the hell scenes freaked me out almost on a Exorcist level. Yet I thought the script was often terrible, especially the part written for Laurence Fishburne who seemed constrained by the script only to saying variations of "Just tell me what's going on!" in authoritative tones.
But wanting to re-visit this title for the horror I finally got the DVD last year and found I REALLY enjoyed the movie. Fantastic horror stuff and mood! It's become a true guilty pleasure and I'm so happy to see it coming on Blu Ray. It has some gorgeously moody visuals I can't wait to enjoy in hi-def.
