Rather typical in movies. The bad guy takes his sweet time getting around to killing the hero.
Check out the end of Lord of the Rings. The wraith dude starts monologuing with the girl, giving the hobbit a chance to stab him from behind. Then the girl monologues and stabs the wraith in the face.
Whenever I watch TV or movie, I always comment about whether or not a character is a “Player Character” or “PC.”
When I played RPGs, looooong ago, bad guys didn’t monologue, because our player characters never stopped to listen. They ID’d the heavies and laid down maximum firepower on them (or ran like hell, depending on how over matched we were...).
In books, movies and TV, the morons will hesitate, listen to the villain run his mouth and let him gain a physical or psychological advantage over them. Or do stupid things like surrender over a hostage (idiots - he’s just going to kill you both...), etc.
Dunno who writes those scripts or why they write them that way. I’d like the show a lot better if some bad guy started to talk and had his brains instantly flushed out the back of his head...
