A thoroughly enjoyable thriller, with plenty of twists and turns. Technically impressive, the action sequences are particularly realistic. Although it is missing a "stand-out" performance, all the cast do very well with the relatively meagre script.

The only criticism I have is that the characters are under-developed, and that the film could have run even longer, but all in all the plot is tight, the action dramatic and superbly constructed, and the visuals and sound are highlights. As competent as they come.

In recent days watched some bad thrillers - even thought starting scenes for them was quiet promising (rust creek, super dark times, whats keeps you alive etc. ); but finally got this one which didn't disappoint. This movie starts to take the pace after the first death of one of the crew members. Then it accelerates even more and produces many more interesting thrills. Loved the scene where Rachel was drowned to a under water lake. Also the final fights are pretty interesting. This movie doesn't loose the plot and holds tight till the end. If you're a fan of a thriller, add it to your list. Acting, music & cinematography is also praiseworthy.
