Blair Witches' marketing gimmickry was also used to a lesser but still hugely successful extent in the movie Paranormal Activity, of course. They just kept on making those Paranormal Activity movies, understandable since they are so cheap to make that they are guaranteed a profit. There are some good "boo" moments in them, but they are relatively lazy cash grabs otherwise. The whole found footage thing was really driven into the ground by hundreds, literally hundreds, of bad imitations. There are just so many; sift through Amazon Prime's horror section for abundant evidence of this. There are some found footage movies that I liked, though. Some of the ones I have seen that I enjoyed:
- Grave Encounters
- Diary of a Ghosthunter
- [Rec] -(its American remake "Quarantine" is pretty good also")
- Hanger 10
- As Above, So Below
- The Last Exorcism
- Host
- Chronicle
The V/H/S series is a mixed bag, as all anthologies tend to be, but there are some great entries in there, especially in VHS 2 which is terrific. The first Hell House LLC is fun, although the sequels are just awful.
The problem is, for every interesting or watchable one, there are 90 terrible movies of this type. There is just so much garbage in this genre. Any idiot who owns a handheld camera made a found footage movie, and that is exactly what they did. One zero budget found footage horror movie that I found on Youtube that I thought was watchable is this one,
Rorschach. It doesn't overdo itself like so many bad horror movies are prone to, and it's pretty restrained which is what these types of movies always should be but rarely are.
