I also love found footage films, but none of them has tugged my heartstrings and made me weep, really.
...
I don't know why I feel I have to justify that, that I didn't cry at any of these movies. But for some reason it feels like an attack on my stoicism or character, the notion you're playing with, that people can cry at all sorts of movies, but 'real men' don't... well, obviously I have some stuff to deal with.
I haven't seen The Bay yet... I'll look into it. Apollo 18 was a bit botched at the end, as BayouStalker said. But most found footage films use the suspense, using anticipation as opposed to actually seeing something, or at least postponing the reveals. I appreciate that.
In retrospect I would have mentioned Cloverfield instead of Apollo 18. But still, a good list of a great horror subgenre.
