To some extent we probably like the movies of our youth in the we like other things of our youth. The ratio or good-bad films is about the same as ever.
One thing i notice though, if i watch a film now it feels different to a 1994 film - but not as different as watching a new film in 1994 and comparing to a 1964 film. I think that isn't just me, but to do with the maturity of film making, the tech and so forth. there was more change in the first decades than later
one aspect of watching even fairly mediocre movies of the past i really like is seeing the background, the street scenes and cars, the details in the location and even some familiar faces of the time. Sometimes i enjoy those things in an older film more than the 'film' as a sotry, same goes a lot of TV.
I suppose the next big changes might be holograms, interactivity, use of VR and so on, on top of partly then maybe totally generated movies.
