Abrader, I think there's actually a happy ending. The sad ending is the original one that the UK audience saw but in the American theatrical release, spoiler (click to show/hide)
the heroine gets away.
It seems that the happy ending is canon now because they're making a sequel. I actually think the cast was pretty good. Sure, they were good looking women but they looked like they were tough and athletic. Women that are into x-sports in real life are not so different from the women in Descent. Overall, I thought it's probably one of the best horror movies of the last 5 years. Which, sadly, doesn't mean much. Can you recommend any good horror flicks? I asked but didn't get much response.
