Omnibuff

A widely knowledgeable geek, nerd, or fan, or lover of all known existing forms, expressions, or genres within an art form or medium, such as film or literature.

She's a cinemaphile omnibuff who happily jumps from horror to rom-coms to French New Wave to Busby Berkeley to German Expressionism to animated Japanese manga to 70s classic porn all in the same conversation while waiting in line for a Woody Allen movie!
