A DARK MATTER is an indie thriller from Canada exploring the sci-fi genre. It goes for a cerebral approach but something is lost in the translation from ideas to screen because the end result is deathly dull and completely insubstantial. A guy's girlfriend leaves him and he goes crazy, that's the basic plot of the thing, but the story feels lifeless and lacking in energy and momentum to keep it moving along. In terms of effects, there are some cool contact lenses but that's about it.
