Drag Me to Hell (2009)

A loan officer who evicts an old woman from her home finds herself the recipient of a supernatural curse.

Sam Raimi's triumphant return to horror.

This movie is so much fun.  And so Raimi.  I can only imagine how many theatergoers went into the cinema thinking they were watching the next Saw or Hostel, and were just completely befuddled by what they were seeing.  In true Raimi fashion, physical comedy is once again the name of the day, almost making this something of a spiritual Evil Dead 4.  Which is fine by me.

Some people seem to dislike the ending, but, come on, it's horror.  What do you expect?

I Saw the Devil (2010)

A secret agent exacts revenge on a serial killer through a series of captures and releases.

One of the most feel-bad movies on this list.  If that sorta thing isn't your cup of tea, don't even humor the thought of watching this.  You're just gonna have a... "bad" time.

When this was released much was made of the "who is the true monster" nature of the plot.  But I think it goes beyond that.  Much like with the earlier Funny Games, I think the true diabolical trick here is to try and punish the audience for making them think they're gonna get what they want, and punishing them even for wanting it in the first place.  Very cruel.  Not as cruel (or as meta) as Funny Games, but up there nonetheless.

The Cabin in the Woods (2011)

Five friends go for a break at a remote cabin, where they get more than they bargained for.

Yet another modern horror classic.  The 21st century really has been a great time for the genre.

Chances are you already know what this movie's whole "deal" is.  If you don't, don't dare look into it before watching this.  Trust me on that one.

But the amazing thing, is that even when rewatching this, and knowing what's going to happen, it loses none of its replay value.  There's always new things to catch, or tiny little details to notice.  And the cast is so good, especially a certain "duo."  I'm incredibly thankful no one ever tried to do a sequel to this, because the only thing it could have done is tarnish the legacy of a perfect movie.
