This film has a very slow pace as the director is trying to create an ominous atmosphere, but the buildup doesn't need to take so long. There is no real flow to the film as most of the scenes feel rather disjointed going from one to the next. To be honest, the film never actually gelled for me.
Also, all of the main characters aren't very likeable. I never really cared about what would happen to them. One of the characters is very obnoxious & irritating. So much so, that I was hoping she'd be killed off soon. But nope, no such luck. You'll know what I'm talking about early into the film.
There are some clever ideas in the film, but not enough to sustain one's interest for 2+ hrs.
So, is this film worth seeing? Nope!
