I agree with your review. To me one of the most important parts of a good horror/mystery/thriller is having characters you actually like. That pulls me into movies pretty easily. At the very least you need characters that seem somewhat based in reality so you can put yourself in that what would I do/what will they do type of mindset. The Invitation had none of that at all. A bunch of people that no one would want to be friends with doing stupid shit with the only reason to keep watching being the mystery aspect which was a letdown in the end. Maybe a big creepy supernatural ending would have been a saving grace but nope. Just jerks doing jerk things. Speaking of new to netflix Road Games is on there now. I wanted to see it for awhile after hearing a couple good things but I didn't have time. Now that it's streaming I hope to catch it this weekend!
