The other reviewers have pointed to this being a 'kind of/sort of' prequel to "Reeker", which I did not see. The other reviewers also said that if you saw "Reeker" then "No Man's Land" will be kind of a letdown.
Without having seen the 'Main Event', I think I agree. But if this is your First view, then by all means, it will be entertaining.
Without giving away any plot-- a assemblage of characters, including the obligatory 'Fleeing criminals' are holed up at an isolated desert gas station/motel to find they are trapped and being stalked by something Hideous.
Starts as a simple, time-worn horror/slasher premise, which can prove to be limp and boring except for either creative laughs or extra buckets of splatter. You know-- a "Jason" in the Desert sort of thing.
Except-- this movie takes a vague left turn. It isn't about the Splatter-- though there is a bit of that. It's about some strange, unexplained supernatural rules: Rules that must be adhered to. . .or enforced.
Think about it that way as you watch and begin to scratch your head-- then when the end comes, it will all try to snap together. Yeah-- with gaps and loose pieces, but still. That's why I gave it a 7. That plus the notion of a 'Reeker' as a supernatural creature seemed more corny than scary at first glance-- so you think it will be cornball fun and yucks might be disappointed when it doesn't deliver.
Instead, I came away from this movie thinking of an episode out of Neil Gaiman's Sandman universe. So to me, this movie was more Supernatural Thriller than Horror. Not the BEST-- but nicely entertaining. Give it a try.
