Be sure to watch the "bit characters" closely for familiar faces. The music was surprisingly good, but what could possibly be bad about anything that involves Elle King. Do stay through the credits. There's a piece at the end that is stellar.
Wigg and McCarthy are very believable besties, and McKinnon pulls off psycho scientist well. It's Leslie Jones who steals the show. Neil Casey was less pleasant, but I don't know if it was his acting or the character.
See it in 3D if you get the chance.
