I don't know that I am a "nerd" for recovery per se but I do get bent out of shape when people do 12-step meetings "wrong" in movies, TV, etc (I love the Carmy monologue in S1 of The Bear for ex. but at a real meeting the chair would be like "Jesus guy wrap it the fuck up already")
I have a personal belief that the more a person is a nerd for something: dinosaurs, The Odyssey, etc, the less likely they are to enjoy a popular entertainment version of that thing.
