Quoted from aobrien5:

Who all died during that raid?

Quoted from TopTierArcade:

AHH! I was thinking the same thing. Would be cool

Quoted from Mfsrc791:

His name is the mountain. He is the hounds brother. He was brought back to life by maester qyburn, who lost his maester rings for doing so. So basically he is like a zombie guy

Quoted from Luckydogg420:

That's the mountain, he's the hounds brother; he's the one that gave him the burnt scar on his face. The mountain died during trial by combat to save Tyrian (the imp). He was killed by a poisonous spear tip stab right before he crushed in the skull of Tyrians hero.
He was resurrected by Qiburn, the man that is now Cersie's "Hand of the King". He was a maester that was kicked out of the order for doing crazy experiments with the dead/living. It was interesting how he dealt with the undead soldier at the meeting. He didn't seem scared as much as fascinated by it. Maybe he will play a role in season 8 when the dead are knocking on the door of kings landing.

Quoted from Luckydogg420:

Sam will be safe in old town. Writing the whole story....the story of ice and fire.

Quoted from merccat:

I imagine the Starks are simply going to burn his body to prevent any raising by either side.

Quoted from HoakyPoaky:

Berric raised from the dead six times to finally die unfulfilled under a mountain of ice???

Quoted from ForceFlow:

Yeah, a lot of plot holes and dead ends. Kind of disappointing considering earlier seasons were constructed so carefully and thoroughly.

Quoted from Eskaybee:

Fantastic season, and even greater finale. I can’t see how anyone who’s a fan of the show not like this season. Yes, it felt rushed and should have been drawn out more, but let’s reflect on what we got:

+ Night King storyline: we’ve seen and were introduced to white walkers and the undead since the beginning. We’ve seen suspense as our favorite characters just barely live their encounters. We’ve seen the whitewalkers decimate the free folk; we saw Jon Snow take on a white walker and killing it with Valaryian steel; we learn that taking down a while walker who has raised the dead will eliminate the undead bonded to him - i.e. how do you beat the undead, ‘kill that fucker’ *pointing to the night king*; we’ve seen them surround the bested baddest warriors in the story in which the night king takes down a dragon and summons it as his own; we see them absolutely annihlate the wall and move on to the land of the north; we see Jon snow gather the strongest army in the country to take on the undead in an epic battle in which we see and learn that Jon’s army is no match for the undead and that no one can stop them until an epic assasination by a fan favorite in Arya Stark. That storyline had to end, it was either kill the night king and save the world, or die and everyone in the world dies. They couldn’t draw that storyline out any further.

+ We got to see 3 dragons be raised from eggs, to lil pups, to some huge ass holy shit arm hair raising dragons. We get to see the destruction they were capable as they become full grown. We get this eerie feeling of weakness that Daenerys may be no match for Cersei having Euros and the iron fleet with the scorpion crossbows, but learn that his fleet is only a threat when they have the element of surprise and see how weak they truly are when they are the sitting ducks. We see an absolute onslaught of fiery destruction with Drogon reaping down on a city we, the viewer, once despised, and slowly (yet again via GOT tradition) learn that Daenerys has always been mad with destruction - eye of the beholder. I almost bought into her speech to Jon Snow at the end, believing she knows what’s right for the land, her true colors are shown that Tyrian was right, she was more evil and devastating than his sister.

+ Brans storyline comes full circle; he didn’t want to be king of the north, but he said nothing about being the king of Westeros. And we see that in the end. Sansa becomes queen of the north. Arya goes on another adventure, and Jon is banished to the nights watch where he gets to help the free folk rebuild their lives which is something that has always been true to his heart. Everyone wins. The only threat and unknown is that Drogon lives, and Daenerys.....?

+ All our other favorite characters (Sam, Brienne, Yara, Ser Davos, etc...) all end up in a position of high power.

All in all; they finished the story quickly, we all agree on that, but we got some epic battles and a finale that brought everything full circle.
