Sure it will probably work fine in the Unitedstates of Dumbasses as they obviously took the decicion to make it "horror for dummies" and have Abby explain that she needs blood to live.
"I Need blood... ...to live" Way to go fools, stomp allover the unique reason the first one works so well.
The fact that they never declare what Eli is in the original - although people suspect it, and Oscar asks her in the scene recreated in that trailer - nobody ever confirms that it's a vampire.
Now don't get all worked up, I'm sure that the movie will do just fine, but it's not going to be the suave classic that the Alfredsson flick certainly is, and I'll most likely watch it due to the Hammer connection. Oh and because I like the original so much that I have to give the remake the benefit of the doubt. But as said, with that trailer in mind, I'm kinda questioning it allready.
Anyways, here's some stuff that I've written on the original previously and also a second chance to check out the interview I did with author John Ajvide Lindqvist about his books.
