"The Cabin in the Woods" is easily one of my favorite horror movies. It's either that or "Alien," though I tend to lean toward the latter since that's one of the better movies ever made.

If you think Until Dawn was a decent meta horror movie, Drew Goddard's The Cabin in the Woods does this concept better than any other recent film.

Like a Cabin in the Woods-style Groundhog Day, the group endures bloody zombies, cursed clowns, and an Alien-like pregnancy. Check out the trailer below.
