Is this movie scary?
No.. It's not.
I am pretty sure that THAT is not what happens on the ladies room. Mindless horrow.. It just isn't really scary, you need to have at least some logic. The fact what makes things scary is that you feel - it actually might happen.
For the movie, horrow is not suitable for the flash videos. It needs to look really real to work. Watch the Castle series on NG for example.
The audio was impressive indeed.
But for my opinion, don't do horrow films. You have some real talent, use it to make something what really matters.
