Paranormal Activity

Well after saying i was never going to see a scary film ever again i was sitting in the cinema watching the trailers at Paranormal Activity. I was so scared before it came on cause i was just thinking the worst.
It was a "documentary" on how a women has been getting stalked by a ghost since she was 8 and her husband decides to video her for 16 days.
It was far too well done to be done by an amatuer so the whole feel of it being real was blown in the first 10 minutes of the film. He seemed to capture EVERYTHING on camera, and the tape somehow never ran out either? Also there was far too much build up to the end scene because it just got worse until she finally got abducted and killed her husband.
As the womenin the cinema said "it is only scary if you believe in ghosts"
Also I think it depends on the audience you are with. Our audience jumped at quite a lot but just laughed afterwards and kind of made a mockery of the film which ruined the tension watching it.
I wasn't scared really until the end 10 mins, and then the last bit i couldn't even watch because i didn't want to know what happened. I hid behind my coat and maybe Sam give me a runnin narrative to what was happening.
I felt it was a bit boringat the start as nothing really happened until an hour in to the movie.
The characters were chosen really good as they did look as if they were just a normal couple and the women was not really stunningly pretty for once. The acting played by the man was cringing - and he really was not a good actor, but the women played the part really good and you felt her emotions was really good.
The whole thing was just far too thought out and was only scary in the last 10 mins at the end.
Overall, I don't really have that much to say about the film apart from it was not very good at all, and wasn't what it was all  cracked up to be.
