This question already has an accepted answer from a moderator. Nevertheless, I'm going to dissent. I think that questions of this type can be very helpful, because often there is a valid reason for the apparent discrepancy that the asker just does not know about. It can be the case that subtlety can be interpreted as a possible plot hole.
Without knowing the answer, how can the questioner know if the question is an "obvious plot hole" or something else?
In 2001 and in Total Recall, the protagonists were exposed to vacuum, with very different reactions. One of these is a plot mistake. One is correct science. A question asking about the validity of these effects of this would be on topic for one movie but not the other?
Obviously, there are extreme cases, of course...but I think those would be voted down in the normal fashion.
Here is an example of a question that could have been quickly closed with a comment of "there was no point", but that then got a well documented answer that gives a clear and sensible real response.
