Not as bad....at least better than a 2.2 rating.
I just watched this movie today and i think it deserves a higher rating, it better than most crap Post Apocalyptic movies out there and i think the PA enviroment is really well made..there remnants of our destroyed civilization everywhere..and those remnants, in form of houses, a gas station, old road signs and other stuff makers did a good job creating.
