Great movie but unsatisfied ending

Rating: 7/10 (9 January 2008)

I saw this movie on DVD, when movie started I felt the subject is very interesting, actually director touches the human emotions beautifully with a common concept of horror movies like resident evil etc. The idea is very unique in its depths but at the end I realized that, I saw nothing. There should be more for characters even his dog "sam" should be not killed in the mid of the film.
You can see the movie...over all it is not boring, very interesting,special effects are great...but surprisingly the buildings & cars of new york shine and cleaned among animals and there is no human in the new york except the hero.
Watch it....
