How can a movie be that influential but not a "classic"?
just because something can be influential, doesn't mean it's great. Certain elements can stand out and resonate with the masses while the entirety is still mediocre. Even though it revived the found footage genre, it wasn't seeing the movies that came after.
I saw the movie when it dropped and nobody I know really liked it. Cacs made a big deal about it, but that was it.
