Deathdream

Now many of you are saying this is a "rip off" of Warm Bodies (which is based off a book, and also a retelling of Romeo and Juliet). Nope.

It seems more to be a remake of the 1972 movie called Deathdream. Here's a synopsis I found on rolling stone's website:

Meet the Brooks, an all-American family who've just been told that the eldest son, Andy (Richard Backus), has died in Vietnam. The news is shocking — almost as shocking, in fact, as the clearly contradictory sight of Andy showing up at the front door not long after. But there's something seems...different about the young man. Andy snaps, acts strangely and begins to show the rot beneath the happy exterior of his not-quite resurrection. Also, why have a lot of dead bodies started showing up mysteriously around town?
