I'd prefer all the MCU tags together. Mostly because there are so many TV shows now, and if every single one is separate, then I have to either pick between them or use all my slots on them (not to mention using the crossover fandom slot too since I like to mix and match).

Or, would it maybe be possible to have MCU movies and MCU tv as two categories? Then it's not quite as unwieldy but it also doesn't require having 10 different categories for the TV shows.
