Movie-Shadows of the Dead, how bad is this movie?

Ok I have seen worse, but most I shut off after the 1st few mins. 1 for example ( and I read reviews that it wasn't that bad) was Hells Highway with Ron Jeremy( didn't know that at first)OMG! Mystery Science theature fans watch the head splitting scene in the beginning. Anyway- so many things didn't make sense about this movie- A flat tire doesn't mean you can't drive- the spare tire was no way near the size of the flat. They (mostly the chic)showed no emotion , no nothing about the whole woods experience! The make up is bad -the actors bickered since the beginning(mostly the chick bitched and blamed the guy for stuff that was her fault) But after some more bickering , she says it was the worst fight ever. What was the pic in the bathroom? Who puts a pic in there? If it was the chic , then why after fleeing a body in the wood do they set up a framed pic? They show up at an abandoned cabin and set out framed pic? I may be wrong -I dont know who she was. I feel I was asking way too many question that were just not part of the plot and I knew would never be anwerwed.
