Couple of horror/thriller reviews:
The Invitation (9/10)
Really enjoyed this. The vast majority of the movie takes place at a dinner party. A guy (Will) and his girl go to this party hosted by his ex-wife and her new man. The invite comes out of the blue and it appears that it's the first time Will, his ex, and all of their mutual friends have hung out in a couple of years.
There are a couple of lingering issues that are addressed, and it comes down to Will being paranoid about the vibe of the party... locked doors, late guests, etc... Is Will overthinking it, or is there more going on that no one is catching on to? More to it than that, but I don't want to spoil any plot points.
