Either that or Cersei being queen would've been the correct ending.

The Lannisters would've had the only real army left without that WWE-style defeat of the Night King. Cersei's consistently outwitted everyone (except Tommen, I guess), and they knew how to buy loyalty.

Instead we ended up with the usual plot armor, and a "twist" that the character that behaved like a tyrannical zealot for 7+ seasons was, in fact, a tyrannical zealot.
