Q:

Let's kill all the [character]s

Does this site really need a character tag?
Nearly every question is about some character in one way or another. And character wouldn't work as the sole tag on a question, which makes it a meta tag and therefore undesirable, according to SE central policy.
The purpose of tags is supposed to be for experts in a given subject to find questions to answer on that subject, but there are obviously no experts on characters in general.
I propose the burnination of the character tag.
Who's with me?

A:

I think that this tag is useless. 
No one is going to look for all of the questions about all characters in all movies or TV shows. 
Most questions with this tag are about a specific character in a specific film... Which means that the film tag should be more than sufficient. There's no need to further point out "hey, this question is just about one character"... and the spotty usage of it shows that it's not helpful.
Here are a few questions that are about "characters", have fewer than five tags and yet, don't have the character tag.

Is there any hint as to why Jerry needs the money?
Why was Ian's onset of Bipolar Disorder so fast?
Why did Major Hellstrom get suspicious?
Why did Apocalypse say this?
Why didn't Pietro Maximoff tell Magneto they were related?
Why was this specific character in Age Of Ultron killed off?

And that's just from the front page and it's just the ones I absolutely know "should" have it.
If we're going to use it to classify questions but most of the questions that "deserve" it don't have it... then the tag is useless. Get rid of it.

I don't think that this tag, character, is useless. 
"Nearly every question is about some character". It's good word choice: "near" ...it`s not the same than all. I've made questions about characters myself and I like them: one question with over 5 votes on Hodor, from Game of Thrones, and others less popular questions on Gilfoyle, from Silicon Valley, and even on God, in Supernatural. Maybe vote popularity has to do with show/movie popularity, so that might not be such a huge issue. Just my opinion.
On the other hand they're tons of tags not related to characters, just some to mention: film-techniques, production, animation, soundtrack, title, effects, props, among the most used tags on site.
The second point: that "character wouldn't work as the sole tag on a question" seems sound. However, keeping the tag even as a secondary one can help to do cross searches on a topic, such as different aspects of a movie. For example it's not the same between these two sets of tags:

fight-club, props, ending, production
fight-club, character, dialogue, analysis, plot-explanation
