'Revenge Song' review: Geek theatre rules‪!‬ Opening the Curtain

Did you ever have a nerdy friend in high school? Or maybe you were the nerdy friend? Someone who was super into anime, comic books, sword fights; always had a corny joke or a geeky pop-culture reference; totally into cosplay; also super smart and knew really weird but cool stuff about history? Maybe queer? Maybe not? Super creative, super self-aware but also sort of a mess which kind of bugged you but at exactly the moment you were going to give up on them you realized they had a heart of gold and were doing the right thing? If you could roll all that up into a play, it'd be Qui Nguyen's world premiere "Revenge Song."
