I can definitely get on board with #4. I loved that episode but at some point I got a little bored with all the destruction. The Wars/fights in general have always been my least favorite part of the show.
I agree it was rough after a while but i think the point was to drive home the humanity of all the violence. I think they succeeded. There was a thread on reddit where a guy from Bosnia said he cried watching it because it reminded him of his youth.
Think about the death toll from this show.
Most of Renlys army of 60000 became Stannis' army which got destroyed at Blackwater then got reinforced by the bank, killed the wildlings and lost at winterfell.
The other half went back to highgarden and got destroyed by the lannisters.
The northern army was about 30000 strong, went south, lost 2000 men to capture Jamie lannister, beat up the lannisters a couple more times then got split over the car stark thing and then the red wedding. The remaining men died at winterfell.
The wildlings had 100,000 men but got killed by stannis cavalry and at hardhome. There were 8000 men when they went to fight Ramsey at winterfell and fewer against the army of the dead at winterfell.
The dornish armies and good greyjoys got decimated by euron. Euron lost the iron fleet to dany.
The lannister army, gold company, kings guard and gold cloaks are gone. The freys are all dead.
The nights watch is gone.
The sons of the harpy and the masters got cooked.
The second sons are just city cops now.
And now a large portion of half a million people in kings landing are dead.
The lannister, tyrell and targaryen families are almost completely extinct and a lot of the remaining ones won't have kids because they can't, it's not me, they swore not to, they used to be dead, or they look like bran.
There's still a little bit of the northern army and some knights of the vale, and there's still one dragon and a few dothraki and unsullied left, but there's still an episode left.
After all of that death... is anyone in a better place than king's landing under king Robert?
