Tempo was dragging, acting was okay, overall, not a great but not too bad of a movie.

It was a good thriller

I felt as if there was too much dialogue between the main characters of the film and less on the stressful, life threatening scenes. I really appreciated getting to see the film for free - but wouldn't pay to see it and wouldn't watch it again.

Very suspenseful! But ended horribly! Left you with what happened to the sister? Did the others really die or was she halcunating due to the increased oxygen? Loved the actors.....movie was good overall. I'd recommend.
