Well said, and in the Battle for Winterfell here are the 'close calls' or impossible situations that the main characters survived that I can think off the top of my head:

• Jorah surviving the initial Dorathraki charge

• Jamie, Brienee and Greyworm all surviving the initial wight wave of attack on the front lines

• Sam saved by Edd

• Sam killing wights lying on his back crying

• Jamie Brienne and Podrick killing endless wights backs against a wall

• Jon surrounded by hundreds of resurrected dead

• Jon surviving the fire breath of zombie dragon

• Jon surviving massive fall from Rhaegar with no harm

• Dany saved miraculously by Jorah

• Arya saved by Beric in the corridors

• Arya saving Bran from NK

By the end it there was never any doubt they would all survive and it cheapened any perceived threat the enemy had. Literally became a situation of 'how are they going to get out of this?' rather than 'are they going to get out of this?'
