Admittedly, this is a sub genre that I am not too knowledgeable about, but I have seen a fair few. I like found footage films, some are rubbish, and some are great - that bring some much needed originality. I go through phases, where I was a lot of FF movies, to where I may not see any in months, but I always find them entertaining. .I never do anything by halves, so I will list what I really liked. (In order, for the most part)
