The storyline is pretty old and I bet you've already seen it in a few other movies yourself:
- A group of people are trapped in some place or another (in a cottage in the woods, on a boat, in some old castle or warehouse) - Someone or something evil is set loose
- group tries to escape but mysterious things prevent them form escaping
- instead of staying together, some girl will separate from the others and follow a creepy noise into a dark place ("hello? is there anybody out there in that creepy forest / tunnel / cave? Maybe the psychopath that killed my boyfriend / husband / friend 10 minutes ago?")
- another girl will try to run away, being chased, then trip over nothing, and stay there screaming while "the evil" hunts her down etc.
You know those ingredients - you've seen them often before.
The only thing new here to me was the setting in an underground self-storage, which I thought had some original ideas that served those few scary moments.
I feel kind of sorry for the director. It feels like this is the desperate (but futile) attempt to fulfill his lifelong childhood dream of producing a super scary blockbuster. In a "i can do it" and "nobody can stop me" brute force way, he tries to patch up all those holes in the illogical and inconsistent story just to quickly get to the end.
If you don't watch this - you won't be missing out on anything...
