This was a find!
It’s British. Basically a bunch of executives for a defense company go to Eastern Europe for a corporate retreat and very bad things happen. It’s got some good tense moments and is not shy at all about the gore, but the horror is tempered with quirky humor and just a soupçon of class politics. Plus Tim McInnerny!
One of the reviews said it was like “Saw meets Shaun of the Dead”, which isn’t exactly right but I suppose describes it as well as anything. A good time.
