The potentially creepiest guy

I thought the guy who played Dan was HILARIOUS. He was the friend that they were suspicious of being a serial murderer or something. I didn't want to laugh but his delivery was so good. I was glad there were outtakes of some of his improv at the end because he was the best part of the movie. His friends interactions with him were all I needed and I wish the movie would have been just about that whole dynamic instead. Gil Ozeri was underused!
The main characters were OK. I too thought the girl was trying way too hard to be like Kristen Wiig, but the guy had some good moments.
