I'm not sure if it was intentional or scenes cut from the movie found their way into the trailers, but I was a bit disappointed when I noticed key points were not shown.
I was looking for the scary hand in the shower scene...... CUT.
The part when she indicates "someone" is sitting in the chair........ CUT.
I didn't enjoy it as much as I should have as I was focusing on the parts I'd seen in the trailer and thinking.... when will they feature in the film??
A good, tense movie nonetheless
