Idea: show the 250 best movies of all time list for each demographic (age, gender, US/non-US, etc.)

Best according to age groups?
Best in every Group?
Best in 30s 40s 50s 60s 70s 80s 90s 00s Current? 
Best in Silents?

30s Gone With The Wind; Good- By Mr. Chipps, 
40s The Third Man; The Heiress,
50s On the Waterfront; All about Eve,
60s The Graduate; Dr. Zhavago,
70s The Godfather I, The Godfather ll
80s Raging Bull; A Room With a View.
90s American Beauty; Four Weddings and a Funeral.

I am giving films that are a delight to watch more than once, stimulating, and well written. C.j.Blanda

I'm confused. Since when do movies have "gender"?
