Cabin in the Woods maybe my favorite horror movie from the past 10 years if only because it ties all horror movies into a nice little package, disposes of the package and then challenges us to make something new. Like an ambitious historian, this movie tries to tie every horror movie together under one mythology and I think it works very well.
The basic plot is that a group of college students go to a remote cabin in the woods for a weekend of relaxation. Almost immediately, we know something else is going on as we keep cutting to two middle-aged guys (played by Bradley Whitford and Richard Jenkins) who are just passing time and seemingly know more about what the weekend has in store than the kids themselves. A creepy local gives a vague warning about the cabin, the characters find themselves falling into roles they don't inhabit back home and an eagle crashes into a force field the group passes on their way to the cabin. Things are about to get weird.
The less you know about this movie going in, the more fun it is. What I've already described is pretty spoiler heavy but just know, there are lots of turns in the plot still ahead once the crew gets to the cabin. The script is funny and colors within the lines enough to work as real horror once the evil starts attacking our heroes. The entire third act is so batshit insane, I can't go into it but it is a lot of fun.
If you love horror and want to see even old movies in a fresh light, check this out.
