This movie is fucking great for the first 80% or so. I was ready to come in here and drop a 9. Its really well made, the jokes are funny, the main characters are all likeable enough, the killer is cool but also cruel so you can't root for them and they do a really good job of luring you into a false sense of security right before Heart Eyes strikes. Was shaping up to be a slasher classic.
The killer reveal is Huge for these types of movies though and I think they fumbled it a bit though. Every single clue in the movie points one way, and that would have been the smart way to go even if it would have had the audience going "oh I totally knew they was bad from the start." It reminded me a lot of Thanksgiving acually in that
Twist! The most famous person in the movie is also the killer! Even though there's now way too many unexplained coincidences revolving around the boyfriend.
Yawn. I hate that. But ... I'll forgive the writers for trying to be overly clever and subvert expectations at the expense of a logical conclusion. The movie was still very good and I hope we get a sequel with all the surviving characters. 8/10
