^^^ Strong action sets episodes will ever look good on the IMAX screen, and the Season 4 finale would be one of them. I loathe IMAX/ HFR/ 3D, so I can't imagine watching those sit-and-snark episodes on IMAX...
Although the CGI is quite good in general, they're still quite a bit off-- and lacking in terms of creating a convincing epic scale that certain scenes demand. The Dragons are well done, but some scenes, like the Wildlings invading the wall and Dany's army invading the city, lacks in awe, particularly Dany's invasion. And Stannis's army invading the Wildlings was poorly-rendered CGI. I know they spend most of their effects-budget on the Dragons-- and they look the best, but it's clear they need a bigger budget if they are to pull of such grand feats if there are more in Season 5.
... And I loved loved loved Brienne and The Hound's brawl. It was an all-out brawl and it didn't hold back: It was mean, intense, bloody and great fun to watch, and so glad there weren't any tight edits, instead they were wise to just let the fight unfold between two equally matched fighters.
I hope the show doesn't decide to kill off Brienne...
BTW, Jaimie's pointy, beakish features are really distracting with the shorter hair LOL He needs his hair longer again. He's like Daria with her short hair-- very unflattering.
