We've seen this a million times before and usually much better done.
There will be references to other movies that this one resembles and those are valid opinions but this movie on its own merits is pretty worthless. I won't discuss the movie in detail (there are many other threads that do) but the ending is what gets me. Every damn movie that's made today has the typical "non ending" as though they are keeping their options open if this movie made it real big and another one would be in demand, problem is 90% of the time that won't ever happen on a b-movie direct to video release. They should just accept that and give a solid resolution to the ending. Having an open ending for the sake of a movie that will never get made is both pretentious and insulting. Since there is no real ending why did we just sit and watch the whole thing? Pointless.
This was the second movie I watched today, the first being leprechaun origins which I gave the same rating to (a "4") and it also ended with an open ending. If forced to say which movie was better than the other I'd have to flip a coin.
