Sometimes I wonder if I'm watching the same film as the other critics? 'Downrange' is a pretty straightforward gore-fest, low budget flick, cast of relative unknowns ... for me it works well, tension is maintained throughout the 'phases' of the film, particularly during the various 'standoffs' when the characters work out what the hell to do. If you go into this movie with realistic expectations you come out satisfied. Director Kitamura makes slick horror and fantasy films obviously even when he doesn't have a massive budget to play with. And lastly, leave the actors and script the **** alone, it's not half as bad as some of the rubbish I've seen recently.
Be honest, we all love a bit of cheese occasionally :)
