Since this thread opened EVENT HORIZON has been on my list as a good movie, but not one of the best. Great premise, haven't seen it for awhile but I remember the effects being impressive, but the story is so-so and as electric indigo put it the second have doesn't do that well. But Lawrence Fishbourne & Sam Neil did a great job though.
So yes, its a fun movie and will scare the cr*p out of you if ya haven't seen it before and at night with the lights off! (Sweet Dreams)
