user274: Related: Are there animes/mangas we want more questions for?
The above question was related to what we should do about skewed tags and whether there were specific tags we wanted questions for. But it really didn't gather much in the way of a list; one answer came close, but it is limited, and difficult for us to still use that after so long.
So, in order to give an idea to users who want to help generate new and interesting content: What anime or manga series do we want more questions and content about?

user91: On ANN:

Top 50 anime, best rated, highest rating using bayesian estimate
Top 50 anime, most viewed, highest number of votes (good or bad)
Top 50 manga, best rated
Top 50 manga, most viewed

Combining these 4 lists, removing duplicates, and removing what we already have tagged, we get:
