Well, im a day late and a dollar short on this thread, but I couldnt resist not giving my 2¢. My opinion of changing AR is 2 fold. First, I HATE IT!!!
Then you DEFINITELY don’t want to see Kong: Skull Island! I watched it last night via HBO streaming and the aspect ratio literally changed shot-to-shot for the entire film. It drove me nuts! Haha I don’t mind it if it’s for a scene here or there, as in TFA, but this was horribly distracting and amateurish.
Yeah, it also drive me crazy in Transformers The Last Knight!
