I don't say that this is the best thriller ever, but it sure is surprisingly entertaining, taken the probably modest budget into account. I liked how the movie doesn't waste any time: within 5 minutes all the needed background information is given, and then immediately the action kicks in with the sudden entrance of 5 masked and armed thugs. The rest of the movie we see Karen alternately flee and hide, or, by chance or premeditated, physically fighting the intruders. This gives the story a high level of adrenaline, and the relentless, rage-driven way in which she kills one after another, with the according pretty well done gore, takes it to the higher (or deeper, if you will) level of a serious horror-flick. The whole thing is very one-dimensional (there's only one modest twist concerning the identity of the last one standing villain), but that suits the story fine. As does the (predictable) ending.
Sure, there are several flaws. Like why doesn't Karen immediately use her cellphone before stupidly loosing it; or how can she find her way so well in this immense and dark factory, it being her first day on the job. But this hardly marred my pleasure. The acting of most of the cast (the intruders) is irrelevant, they all stay masked up until their last minutes. So Natalie Terrazzino carries the whole project on her shoulders. She's not there for her looks, but for her athletic skills and resilience, and she does a great job, she's totally convincing as the frightened but determined power-woman.
