If an ID question doesn't have enough detail, there's no reason to down vote it AND VTC it. Just VTC and move on.
I don't downvote every ID question that I VTC but I suspect that there is a close correlation.
The vast majority of ID questions are poorly contructed and/or lacking in sufficient detail.
As such, they deserve a DV because:
This question does not show any research effort; it is unclear or not useful.
They also likely deserve a VTC because the question does not "contain sufficient detail to meet the site's quality standards".
Unfortunately in the case of a poor ID question the two tend to go hand in hand and, as I said, we get a LOT of poor ID questions.
I use canned comments and these are tailored to each question but the basis is:
Please try to add anything that may help identification. When was it released? Was it in Color or Black & White? What time period was it showing? What country was it likely from or what language was it in? Are there any other plot details you remember? Descriptions of scenes or names of characters or actors you can give? Anything at all? Feel free to  any additional details into the question. For help writing a good identification question, see: Identify-This-X Questions.
This often prompts a response from the OP with information and I can retract either or both votes as required.
Recall, closure is not the end. It's intended to incentivise the OP to improve the question.
If the ID questioners would bother to read and follow the guidance that is available we'd have a much better question quality ratio than we do.
That's why it's so important to upvote the good ID questions. They are precious and rare...let's try appreciating those.
