After watch The Blair Witch Project, I'm hesitant to ever go hiking again, let alone in the woods the movie was filmed in.
Although I didn't get to see it in theaters, I totally believe some people had a hard time watching it, even to the point of getting sick. As much as the camera moves around, I found it a bit challenging to watch, even on the small screen. I wouldn't watch it again, the whole terror aspect comes from not knowing what you're going to see, and what you don't get to see. It wouldn't be as good a film if you actually got to see the Witch, or what actually happens after the filming ends.
