Forget the fact that this entire move is shot by an amateur cameraman while running/jumping/diving/climbing his way around New York City, that fact is well known by now.
The movie carries on in such a way where you are forced to believe that the "disturbance" is following the main characters. It amazed me that time after time, no matter where they went in a city the size of New York that the "disturbance" was there to meet them.
I was also forced to believe a person can not only survive being impaled through the chest, having the object that impaled them removed and have the gaping wound only leave a small blood stain on her tight shirt but also that within minutes she'll be up and running around.
Later she and her friends will survive a crash that personel in safety equipment will perish in.
This movie was awful. If you don't mind it being implied that you are stupid enough to believe everything that this movie asks you to believe...feel free to waste your money.
What's great about it: It has an ending.
What's not so great: The ending doesn't come soon enough.
