Scary & fun, those are the 2 best words I can think of to describe this movie. Facts speak for themselves. The majority of the audience was screaming during this movie last night and when it was over they broke out into a loud round of applause. When was the last time you experienced that at a horror movie? As far as Blair Which comparisons, to me Blair Witch was like a Disney film compared to this movie. I found Blair Witch creepy but it never delivered. This movie delievers. It's tough to say whether it's the scariest movie of all time becuase we are all sacred by different things. But it is certainly a film that you will still be talking about (or thinking about) when you get home.
