The topic of really broad tags, such as media tags, comes up every so often. To this point, the consensus has mostly been that these tags are more beneficial than detrimental. For example, here is the most recent discussion on media tags:
The consensus there was that media tags "aren't too bad" and "fill a gap" that would otherwise require lots of sub-tags for works that appear on multiple media.
However, that discussion happened before gold-tag-badge privileges were put in place last year. This adds another element to the risk/reward equation for these tags, which was mentioned in this question as a reason not to allow "season" tags:
The problem is, gold tag badge holders can now insta-dupe-close anything with their tag. Meaning, if someone managed to accumulate enough questions and rep to get a gold tag in, say, movie, they could then insta-dupe any movie question. In addition, the powers that be have expressed interest in adding more in the future, and particularly giving privileges to silver tag holders.
Just to play devil's advocate to myself: in practice, I don't know that we're at risk for this any time soon. The closest we have are @Thaddeus, about 2/3 towards a comics gold, and @user14111m, who's 2/3 towards short-stories, and they are ahead by quite a large margin. However, we've already awarded several silver tags, and plenty of users are closing in on more.
So, is it time to revisit the usefulness and need for these broad tags?
