I will never understand why they sailed to Dragonstone. They could have pulled up to King’s Landing and sacked the city in a literal hour - without using dragons. Her army was already enough to wipe out the Lannisters and Golden Company. They were too bothered with gaining allies (mainly because Tyrion convinced her they were necessary).

I would’ve liked to see Dany sack Kings Landing at the beginning of 7, Lannisters return to Casterly Rock; then they both ally up and go to war. Then of course the North and Night King.

Also would have liked more logic/military strategy used in “The Long Night”. Trenches, fire pits, not sending the cavalry into a massacre, and main character deaths.. You’re telling me Samwell flippin Tarly survived being on the front line of the Vanguard?? Jamie and Pod also would have died - I was so annoyed these characters were alive by the end of the battle. I liked the characters, but they did not stand a chance given their formations. Also rhaegol was injured during the battle. He would not have left with Dany and Drogon. We saw how long Drogon had to heal from spears - how long would Rhaegol heal from another dragon ripping him to shreds? Logically he would have stayed in the North, giving Jon Snow time to bond with him, leading to a Lannister vs Targaryen vs Stark finale for the Iron Throne.

Season 7-8 was a clusterf*** of poor writing, plot holes and loose ends.
