Timeless or Of Their Time?

Hi All,

I recently read a film review that began with this:

"There are countless stories one could tell, so why do people choose the ones that they do? Everyone likes to think his or her film is “timeless,” and the best works have universal qualities, but still it would astonish us if a director created a film in 2000 similar in theme and feeling to Intolerance (1916) or She Wore a Yellow Ribbon (1949), or even The Long Goodbye (1973). For better or worse, contemporary life and historical development must have some impact.’
.
Do you guys think some films have themes and feelings unique to the decade they were made in? If so could you describe the themes and feelings unique to films from specific decades?
