Yeah I saw the first in theaters, and followed their website, which was very convincing at the time.
I liked the first film, and will watch it maybe every 3-4 years or so. I know many, many were affected by the shaky cameras, and while I wasn't, I think this was kind of a double-edged sword since it helps make the movie seem authentic yet a portion of your audience is not at all enjoying the experience.
The first movie sets up a really creepy atmosphere due to the lore they created with Rustin Parr and the witch, which I really liked. Not only was it intriguing and convincing, but it offers a great setup to direct the audiences' imagination when much of the creepy occurs off-camera, out of frame, or in the dark. Being a small budget film, this worked out really well.
I saw the second, it was awful. I liked the Goth girl! This was the first time I saw the Burn Notice actor in anything. He's still Burn Notice to many of you, but he's BW2 guy to me.
I never saw the remake, but I did see a clip. A bright light, followed by the appearance of the witch? Not sure what's going on there. The same filmmakers did a movie about aliens, so who knows.
If there's another Blair Witch coming, it's probably going to be a Redbox premiere. Is it a sequel to the reboot, or a third reboot?
