I don't know how old you are, but as a younger millennial these look pretty awful to me (no disrespect). I'm sure nostalgia plays a part. I feel the same way about videos/sci-fi shows from the 2000s - none of the modern stuff quite feels the same.
But as another commenter said, I don't think it's the camera itself - it's the stylistic changes in lighting, camera angles, direction, etc. Each decade has a distinct 'feel' - films/shows in the 80s don't feel like the 90s, or the 2000s like the 2010s, etc.
It seems to be too much now to me. Overproduced maybe is the word? Too vibrant of coloration, too much lighting, too much movement. The best way I can put it is that new shows and movies feel "plastic" compared to older stuff.
