A recent identify-this-movie question got downvoted fast and got the usual "more information" comment. The question asks to identify a movie by a single scene but gives no further information about country of origin, language, estimated year of release etc. The scene described is catchy, though, and while the answer wasn't accepted yet it was sufficient to identify the movie.
Are we too strict with such questions? If I imagine myself with such a question, with a single iconic scene wandering around in my head without reference, I now would feel quite discouraged to ask. Any vague additional information wouldn't help much. "I have seen it a few years ago but it could be old"? "I saw it in English but it could've been dubbed" "I have a (weak) feeling it's from the 90s, possibly 80s" (+4)?
Note that I think about identify questions for movies by an unique, iconic scene that someone who knows the movie will probably recognize on the spot. Vague question with general concepts or plots are a different cup of tea.
