Simply the scariest and most exemplary horror movie in years. All of you people shrugging your shoulders and complaining that it bored you are either lying or completely oblivious. (My guess is the latter.) Just a brilliant demonstration of how effective the most basic premise can be in the hands of someone with the ingenuity to use bare-bones resources to their utmost advantage. Amazing that 10 years later, here I am repeating the same arguments I made when 'Blair Witch' first arrived.
