The monologues in Class really were poorly placed. Moffat's bad enough with his scripts in recent years being largely monologues, but at least for the most part they are in circumstances where people talking excessively isn't that big a deal, although Clara delivering a lengthy monologue while the raven of death flew towards her is definitely a very WTF circumstance for a monologue.
The problem with the monologues in Class is their placement just makes no sense. Someone fighting an alien king and has beaten the king to submission, has him on his knees, with a sword to his neck and all his followers watching is not just going to deliver a five minute monologue on the matter. There's no way the defeated kind is just going to kneel there the entire time and not try to attack again thinking you're too distracted with your speech to be a threat. Likewise, his followers aren't just going to stand their patiently while you say your piece while their king is being threatened. If they like they're king, they're going to attack and defend him during the monologue. If they don't like him, they may just decide two birds with one stone, the unpopular king and the overly talkative challenger.
Even in prose, I'm not sure how that would work. Maybe as thoughts the character would think while fighting, but once an enemy is in submission a quick a decisive finishing move is in order, not a speech.
