Essentially, specific-scene is a pointless meta tag that doesn't really add anything. (not like anyone is going to follow/be an expert in "specific scene"). It's basically synonymous with plot-explanation. Should specific-scene be removed?
As suggested, I have suggested the tag as a synonym for Plot Explanation https://movies.stackexchange.com/tags/plot-explanation/synonyms and it can be voted on there.
Due to the complexity of the issue, synonym isn't the best choice. Instead, the following is needed.
Untag specific-scene from 35 ID only questions, film-technique x 5 out of 6, realism × 3, alternate- version × 3, effects × 3. These make up 1/4th the current tag, and are the only ones where ss does not mean plot-explanation.
Merge the rest, which is 48 (1/4th) already bearing Plot-explanation, and the rest mainly movie title tags, where ss does mean plot-explanation.
Burn specific-scene to prevent future usage, as this tag is specifically useless in describing the content or the question in mind.
