re: “The Long Night” is the worst reviewed GoT episode

Simple enough solution- if the episode ruined it so bad for you, just quit watching it. Don't worry about the last 3 episodes, and let it go.

I totally get that Arya was a surprise nobody expected, and if any of us (myself included) wrote the show, it would have been Jon. And yeah, I also would have had Night King end later in the season, because it does seem like the culmination of the show.

But it didn't happen that way, and I thought the episode was good. All these complaints are just nuts.

Visuals were too dark- of course. It's on an HBO budget, not on a Star Wars main episode budget. They wanted to show a battle with almost half a million participants, including 2 dragons, a giant or so, and a big mounted cavalry. So it's set at night within a sudden blizzard, to blur things... you do that on a sunny afternoon and we're talking 10x the cost. They sacrificed some visuals in favor of scale. I thought it worked, I was able to see the important things. I couldn't always see which zombies were skeletons and which were full of rotting meat, but we didn't need to.

Too many survivors- we have 3 episodes left, and we need characters for those plots, whether as primary or as fallout deaths. I don't have any spoiler knowledge, but if Brienne dies at the hands of the Mountain or in battle vs the Golden Company, that's more dramatic than her randomly dying inside Winterfell.
Tormund not dying; that means the Free Folk seem still to have a part in play. Or that Jon needs an ally/advisor who doesn't hold his tongue. Or, he just gets to live. We don't know yet.

The Arya did it complaint- for god's sake, this show is an ensemble, not just the Jon and Dany show. Arya's whole purpose has been to kill those who would do harm to her family. She saved her brother (and Winterfell, and the Starks, and humanity). This was an ambush assassination plan, it was laid out that way. That actually does make her the best tactical choice. Jon's choice would have been to airdrop to the Night King command post with a team of elite commandos, overcome the White Walker defenders while the army is ravaging Winterfell, and take him down in 1 on 1 swordplay before everyone is dead.
