So, if you want a straight answer, I didn't put it on my list because I don't like the movie. I know I put up the reasoning for why my list isn't all about personal preference, yada yada, but it was hard for me to include something I really disliked on the list (the closest I have to that was Friday the 13th, but we can all agree that is now too much of a classic to be ignored). I will admit struggling with the decision not to include it, and I have thought a lot more about it recently after reading more about The Blair Witch Project, and how it was more than just a film. There was a whole mythology invented prior to the actual film with websites and fan fiction all purposes to make the film feel more authentic. It also really boosted an entire sub-genre of horror movies (found-footage films). All-in-all, if I were to make the list again, this would be a struggle once more, and it might end up somewhere because of it's importance to the genre. This list is not anything I have set in stone. It's fluid. In the end, I left it off and included Paranormal Activity, which had a similar impact and style, and which I actually enjoyed. If I'm not mistaken, PA turned an even greater profit than did BWP, so they are very similar in that sense, too. I didn't feel so bad about leaving off Blair Witch because I included a film very much like it with similar impact, even though Blair Witch was more the pioneer.
