The problem is the genres expression using $ne.
The $ne compares two values, which our case is comparing Crime to Horror,
which makes no sense, right?
I did a
command F on the results in the shell and found “Crime” listed in one of the movie genres.
I have to say that this class is really hard, the videos provide some assistence but it could be easier with more elaborate and helpful examples using all the necessary expression operators to acheive the correct results instead of providing just the base experessions. If you want people to use mongo more, don’t throw them in the deep end to have them comb the docs for an hour for one expression.
Sorry, not trying to be a downer but I think that would help a lot of people who are new, and or experienced, use mongo more.
