You never know what you'll get with horror. In this case, as a reliving change, The Invitation is a horror movie that eschews the supernatural (outside of the Twilight Zone-esque final shot) in exchange for a dose of tension that at times is almost too much to bear.

At first played as a dinner party among the middle aged and semi-rich, thrown by a couple that has spent the past 2 years in Mexico, the scenes gradually become slightly more uncomfortable as the movie goes along and you become equally suspicious alongside the main character, grieving father and ex-husband of one of the hosts, Will. Plus it has John Carroll Lynch doing his usual creepy thing.

By the end of the movie, you can't tell if the viewer and Will are totally misinterpreting everything or not, and its not until a disastrous final toast that we learn for sure. What follows is next is the only action in the movie, 15 minutes at most of chaos that comes to serve as a giant release valve for the previous hour and a half.

An outstanding effort, and really defines the "turning of the screw" style story telling at a level not often achieve.
