I just wish Jon/Dany/Bran, or one of them anyway, had some part in the ending. Distraction, warg ability, reveal some info, maybe taking out some WW (when they exposed themselves to protect the NK) to stop portions of the wights a bit earlier before major characters died rather than have Sam just survive magically amongst dozens of them... something more than killing wights. Granted Jon/Dany did get the NK off Viserion at least, which was done incredibly visually going up above the storm into he moonlight.
I know everyone helping one after another itself would be cliche but this is a huge prophecy event they are all involved in after all.. something more than just a sneak attack. No problem with Arya getting the actual kill though, the actual moment was nicely done.
Right now I'm a little disappointed, but mostly because of massive expectations I still enjoyed it. Will obviously have to see how the last three play out to really judge some of the story decisions, and give this a re-watch.
