Television

The battle at Winterfell is a perfect microcosm of the issues. Even apart from the shit artistic work (everything was so dark you could barely see what was happening), almost every scene made no sense:

• they start by sending a bunch of people into the army of the undead only for them to die & turn into more undead
• the catapults etc. are in front of the castle gates where they're easily destroyed
• they put their most vulnerable into the crypts, where dozens of dead bodies lie, while fully aware their enemies can reanimate them
• characters keep getting into situations and scenes where it looks like they'll surely die, only for them to be fine in the next scene
• almost everyone survives what is basically an unwinnable battle
• Bran doesn't do shit
• they shit all over the Azor Ahai prophecy by having Aria "end" the long night via killing the Night King, while Jon Snow has basically no relevancy

I can't think of a single good choice in that episode. It took one of the greatest series of all time, and made what is essentially the climax look worse than a B-movie from the 2000s
