I hated it the first time.
I tolerated it the second time.
Over the other multiple times I came to both appreciate it and look forward to it. I like how Quinto's rage builds up under the surface of his face before he screams.
His rage building up is what made me uncomfortable. That was the part that it started looking like a parody and Quinto is a brilliant actor but still.
: People were bothered by it because of how infamous it became in WOK and how it represented all of bill shatner in his glorious entity.
Personally I wish they did not put it there. For some reason it makes me so angry with the writers and even JJ Abrams who I felt should have known better.
