Good for what it was
As far as post-apocalyptic movies go this really wasn't bad, it was actually pretty enjoyable. If the synopsis is correct they shot the majority of this movie in the decaying remains of industrial cities that have been abandoned and left to rot, which really is a sad commentary of how our country and government abandoned the hubs of industry that once made the U.S. the greatest country in the history of mankind. Those aren't sets, those are real places that people still live in, that's more depressing than the theme of this film. But from a filming standpoint absolutely genius as it saves on costs other than shooting rights.
The movie itself is a character study focusing on three characters. The infected are largely understated and rarely shown in full but when focused on the make-up work was plenty adequate. The plot is relatively simple, the acting is a bit amateurish but I didn't take any issues with it, I thought the leads did pretty well with it. Not much gore but what you see is well done. It's very much in the tone of "The Road", a journey to essentially no where where death is pretty much a foregone conclusion ending with a sense of hope. Some have complained of plot holes but I found they were adequately answered within the film or by common sense as long as you're not an idiot.
I'd rate this, for it's genre mind you, a 6/10. I've seen way worse movies with way higher budgets. If the budget of this movie really was $35,000 then I'll rate it an 8/10 for pulling off some beautiful imagery and some surprisingly good camera work (at times). If you don't like post-apocalyptic movies you're not going to enjoy this, I happen to like this genre so that's what I'm basing my comments and rating around. In an ocean of crap this was pretty good.
P.S. Sara Gorsky has an amazing set of bewbs. Just sayin.
