If those shots were flipped, it wasn’t an accident. If they weren’t, why change them?
To be fair the entire movie was made as it is on purpose, yet here we are. We’re just making a second judgement, and might find that in our opinion some shots work better if flipped back.
Of course you guys are allowed to change whatever you want, that’s the beauty of fan edits. I try not to pipe in about changes I disagree with, as there’s no point, but I just wonder if you’re going at this one from the wrong perspective. If you’re unflipping shots to fix continuity, I think you should just keep in mind that when the editors flipped them they would have known that they were upsetting continuity, but were purposefully doing it in favor of something more important (like screen direction). If you think it’s better the other way, there’s nothing wrong with that, but I just mean you should consider why it might be like that in the first place.
