Change your TV setting to your heart's content (hell, I do it once in a while when rewatching MOS to get a different experience) and make all the fan edits you please. But to suggest that you know better about BvS, a movie which you had no part of and haven't seen is just out of this world to me. Those choices are made for a reason, whether you agree with them or not. That's absolutely fine if you don't end up liking the final product, but really, the people tweeting Larry Fong and Zack Snyder to "raise" their awareness?
I'm also not surprised they modified the MOS "original" screenshots to prove a point. The movie never looked like that to me.
