I am not refusing to believe our perceptions can be warped by nostalgia. I said that our perception was warped anyway and I explained why "X is obviously the better movie" is a nonsense sentence.
That's absurd to imply I am nostalgic about a movie made about 20 years before I was born, even I prefer that one to the new one.
I continue to prefer that one over the new one even when I know more people of my age prefer the new one.
When you say "Hitchcock has not adged well at all" (which I disagree), aren't you simply telling that you are unable to enjoy things that are not a part of a current story-telling/technology "trend" ?
I do enjoy old things mainly because it brings some sort of fresh breeze to the current aesthetics of cinema. Old things are new to me.
One of my favorite musical composition of all time was written about 300 year ago; implying by this that my mind is warped by nostalgia and that I'm biased is pure nonsense.
Music has changed, but I reject the idea you implied that this change is an " improvement"; I don't think art is improvable stricto-sensus.
