I'm fairly new to Mongo, sorry if this has some simple answer I've not grasped.
I want to be able to count the number of times each number(genre id) appears in all of the 'movie_genres' arrays and get back counts for each number. My end-goal is to tally how many times a certain genre number appears in the user's account (includes all movies).
