Part of what is a favorite is what communicates to us, personally. Potentially, any decade's movies could communicate to us, strike us, but the likelihood is higher that a movie that is closer to our cultural heart will do so. In other words, most of us are people of this era. The cultural assumptions and communications of previous eras may strike us, but more movies of this era should communicate to us.
This. Well said.

Overall I think it's a good list, the diversity of it impresses me. Though just one more of you needed to put Jurassic Park
on your list for it to crack the Top 100
Also a good reminder of some films I need to get around to. Caught Double Indemnity
on sale out of the corner of my eye when out shopping today. And Wings of Desire
is playing in a local theatre next week.
