LOL. I actually watched the sequel and not the first one.
You have to watch the first one
. The sequel is terrible. Trust me, you are going to love the original movie if you give it a chance.
This one: https://en.m.wikipedia.org/wiki/Blair_Witch_(film
Haven't watched Cloverfield too.
I kind of liked it. If you are into Godzilla, you will probably love it.
Blair Witch project wasn't the innovator of the genre. The one that set the standard was Cannibal Holocaust. The film was so controversial that the director was arrested and was banned in several countries.
"Cannibal Holocaust," despite being highly controversial, does not fall into the category of found-footage. I have seen scenes of it. It is very difficult to stomach (and I have seen tons of horror movies). I refuse watching it mainly for the reason that animals got killed while they were shooting the movie. "Cannibal Ferox" is just as gruesome.
I haven't seen "The Devil Inside."
