What the hell did I just watch?

Rating: 1/10 (1 April 2015)

I was so excited to see this film. I have loved horror movies since watching "Creature Features" with my father and brother when younger, and I am pretty easy to please. This movie was a total waste of time and money.
****Spoiler alert*****
Who is the girl in the beginning? Is she a lover of Jeff/Hugh? She is killed so then Jeff has to find someone else to sleep with?
How does Jeff know that "It" is following him because he had sex with a girl in a bar? How does he know if It kills Jay It will come back to kill him? How does he rent a house under a fake name, and why would he? How does he know that Jay needs to pass on the curse by sleeping with someone else? And why would he still see the entity if he is indeed clear of the curse?
When Jay and her friends go to the school to kill the entity it looks abandoned, but the electricity is still on and the pool is filled and in pristine condition. Where did all the electrical appliances come from? They were carrying some bags, but I don't think they were filled with irons, hairdryers and TVs. What was the point of trying to "kill" a ghost? It had already been shot, and that didn't stop it.
Why didn't Jay take 2 minutes and clean her bedroom door?
And the ghost/entity/phantom just comes after you at a walk? It reminded me of a line in Stephen King's book Desperation. "The mummy's after us. Let's walk a little faster"
This movie was another gigantic disappointment.Please stay home and save time, money and anguish. I can not believe this movie was rated 7.6 out of 10.
