Could be better but they failed We have started with a great idea, a movie with some specific bad aliens far down in the water.
But unfortunately the movie sounds too dark (visually) and scenario is type B (instead A) even Vincent Cassel was around there.
They should add more lights ON, more details and a more elaborared scenario and probably it will need some more time (2 hours instead 1 hour 35 minutes)
Also actors (except the main) doesn't show really in type A movie again, they could use 20-25 minutes before the incident start to show what they doing, how this isolated place works, but no sounds too fast and too dark really.
