Looks are purely subjective, there’s no objectivity about it.
Well… No.
Yes I get the whole “personal taste” argument and while I agree that what you personally like is subjective, there is objective quality.
This is obviously a drastic example/hypothetical, but let’s say two movies come out and they both have a scene of a teacher at their desk, an apple at the foreground and clearly the main focus.
One film has a real, nice, shiny looking apple, and the second film literally just has a red splotch that looks like it was put in there using Microsoft Paint, with the intent of it resembling an apple.
One apple looks well on film, the other is a piece of shit.
You may think the second apple looks good personally, but that doesn’t mean it looks like a good apple in general.
