I've had a thought, perhaps Snoke wanted to trag out the blowing up of the resistance so he could show Rey that their was no point fighting anymore. Scraping the barrel I know, but it's similar to what The Emperor does to Luke in ROTJ.
General Hux didn't seem that bothered about rushing to blow them up, maybe he had orders from the top. :?
Did think it was funny how every time you saw the scene of the rebel ships getting blown up two or three got taken out in the space of a couple seconds, but their always seemed to be plenty in the next scene 5 minutes later. They should have all gone in about 30 seconds.
Well done Mr.Tie for giving it a chance and being honest.
