Just the title is quite horrifying ... we just don't know what is behind us. Or what is in the dark and so forth, right? So horror can be made simple (camera tricks, lighting),but it does make sense to have a story. This has one - not the most intriguing, but still a solid one.

There are far worse movies out there - there are far better ones. If you are into horror, you might find something here you like. The acting is good for the genre and it overall has a nice pace with enough (jump) scares to keep you on your toes. Also the make up and blood effects are good, which is quite important. It may end with a horror cliche, but then again: did we expect something else?

Bad.

It's not a good movie.

A good friend wouldn't let you watch this movie.

This is a strange one. I gave it 4/10. I could have gone lower but what stopped me was the performance of the actors who tried their best with nothing to try, and the production value and I did get some sort of entertainment out of it.

There were many holes in the plot and people just get buried and nobody really seems to look for them. The end is also not very good or deep. The police say this was reported as a murder homicide. By whom? Certainly not the husband of the murdered woman, as he couldn't have had any idea about the problem. Nobody could have known. Absolutely inexplicable.

That out of the way. It is watchable. If you pretend it is an episode of something like The Outer Limits, you can forgive quite a few faux pas' and just enjoy the ride, despite and maybe even because of the bad and often illogical script.

Nothing makes much sense, but you do kind of want to know what comes next. They tried a few twists at the end and even though you may shake your head at another silly thing it won't be in hatred.

I wouldn't recommend this as a first choice, but there is far worse out there and if you happen to have to watch it, you won't cry about it either. Rainy afternoon and bored and nothing else on? Then this will hit the spot just fine.
