Another things that is wrong with this film, if there is anything to add to this great review, is that the writers seem to borrow from other movies a bit too much.

- The Skynet tower felt a bit too much like a futuristic version of “Lord of the Rings: Two Towers” Isengard.
- The two children in L.A. reminded me too much of Will Smith setting up vampire traps in “I Am Legend.”
- The heavy reliance on gas hog vehicles and an absolute abundance of gasoline in an apocalyptic world brings MadMax to mind.
- The typical degenerate guys trying to rape a good looking girl in an apocalyptic world, and she being rescued by the hero has been done far too many times.
- The aircraft dodge fight scenes brought clear memories of “Independence Day.”
- The submarine set did not feel quite like a submarine set; it reminded me more of an old pirate movie.
- The hero requesting fellow soldiers not to carry out their orders has been done to many times too. “Outbreak” and “Crimson Tide” are just two examples.

Now, a heart transplant conducted in a field hospital, without the proper medications or equipment, performed by a pregnant veterinarian without confirming if the donor is a match, is a brand new and original concept.
