As of recent there were quite a few questions asking for movie recommendations, which are currently off-topic on this site, and those questions arise now and then and are usually closed quite fast and unargued. However, I find myself writing more or less the same custom off-topic reason again and again when closing those, something similar to this:

I'm closing this question as off-topic because the site doesn't entertain questions for recommendation lists. Take a look at the tour and the help center to get a better understanding of how this site works, expecially the on-topic section. You might also want to visit Movies & TV Chat and ask for any recommendations there. And last but not least, you could also take a look at this more general question to get some possible pointers for finding what you're looking for.

Seeing that they are on the one hand commonly asked on this site and on the other hand rather clearly and unarguably off-topic (as to the current rules at least), would it be beneficial to add something like this (maybe less elaborate, but still with the major guidance) as a builtin close reason or is this not deemed necessary?

There are a few problems related to this matter to consider, though:

• Often those question could technically also be seen as primarily opinion-based rather than off-topic. But there are no custom reasons for primarily opinion-based and one would still be advised to write a proper comment explaining the situation in this case.
• Another way of closing those questions could be to mark them as duplicate of this canonical faq question (which was originally created for that purpose actually, I think). And in fact I personally used and advocated that procedure in the past, as it is the most easy way to on the one hand close the question and on the other hand refer the asker to a place for finding the answer he is looking for. However, I'm not sure anymore if that really is appropriate. The specific question isn't really a duplicate of the more general question and it might not always be clear to every user why his question was closed as a duplicate of a much more unspecific question, when the real reason is actually that his question is just off-topic as it is. It is a bit of an "easy-out" (not to say lazy) way to close those recommendation questions.
• We currently already have 3 custom off-topic reasons (trivia, detail-lacking ID, current events), which is the maximum a site gets by default. There are ways to ask the SE übermods for additional slots, but I currently don't know how much consensus and "urge" is required for this. Another way might be to drop one of the existing close-reasons. For this I would only reasonably consider the one about "current events", since that seems to be used rather rarely and is on the other hand a bit fuzzily defined and not always clear when to use it (well ok, not that "trivia" would be that much clearer either, though).
• Statistics about the frequency of recommendation closures (to see if it is a common problem) are hard to gather on the other hand, at least from the close reason statistics, since it isn't a builtin reason yet and, as stated above, the questions are often closed for various different reasons in practice, which makes them quite scattered throughout the close-reason statistics.

So what are the community's thoughts on this matter? Do we want a custom off-topic reason for recommendation questions? If yes, should we drop one of the existing reasons or ask SE for a 4th slot? If not, then how should we proceed to close those questions, as heterogeneous as we do or with a bit more common policy? Or does someone just have any other helpful information for making a decision, some better SEDE-fueled statistics or experience from other sites?

_{(This should be clear from the question, but just to make sure, if your answer is "don't close 'em at all, they're valid questions", then please spare this for a separate discussion, we are not here to discuss if they are off-topic or not, just the way to handle them given they currently are. But if this is really your opinion, don't feel held back to ask that as a proper question on its own or contribute to any existing discussion on the matter.)}
