Here we have nothing new, it seems like your typical a virus wiping out all of mankind, there's no cure and in no time at all the whole of the human race will be extinct kind of movie. But theres something different about the Carriers, something that gives it edge.
There are no zombies in this movie, its just a virus that causes people to die and once they're gone they're gone. The style is ultimately asking the question of, when there's nowhere left to go where do you go? When there's nothing left to do what do you do, and when there's no one left who do you ask for help?
It's a movie filled with drama, a lot of moments which'll have you feeling down in the dumps and some more cheerful moments which balance it out.
Overall: Carriers is a good movie, it looks like a lot of other movies, it has a story like a lot of other movies, but its not like them, its a little different and special. It's more of a thought-provoking film which'll make you ask yourself, "what would i do?"
