Have a watch and I'll think you might like this. Most films of this ilk start well and then end up finishing on a safe predictable note. This film starts out as a predictable ten people trapped in a storm who die one by one (yawn) formula which goes on to end in a way that makes you re-assess the whole first two thirds.
Not a Sixth Sense but still well worth the effort

The movie was ok until they tried to wrap it all up and lost most of it. The extra ending was imho not worth having.
5/10
I have to agree. The very last scene was a pointless bolt on and detracted from the film. It was such as contrived idea that I suspect it wasn't part of the original script. Best to just stop the film before it :) 7/10
