Add movie / show rating as a search filter

[jbeckman1974]

Would it be possible to add to the active filters for movie and show discovery a list of ratings to include or exclude? This is ratings like PG-13, R, TV-14, not user ratings but MPAA style ratings. The intent is to be able to filter out mature content if looking for children's movies or trying to filter out cartoons if looking for more mature content. Thanks!
