A bit predictable, I sort of guessed what was going to happen. The usual clichéd atmospheric effects - thunder & lightening(!!!), flickering lights, lift not working/working/not working, lights blowing, unusual noises in the vents, flapping shower curtain, images in the mirrors, etc etc. Not really understood the ending, I think it had delusions of thinking it was good enough for a sequel by leaving you wondering wtf? 2 stars because 1. It was an original storyline and 2. It did creep me out (a little) and made me jump.....once.
