I don't think it is possible to compare films across time or cultures. So stories can't get better since they are a function of the time, place and power dynamics.
Here are a few films that I think are really good films
Star Wars
The Matrix
Butch Cassidy and the Sundance Kid
Sweet back badass song
Superfly (The soundtrack is a perfect album)
Hero
Crouching Tiger Hidden Dragon
Too Tired to Die (Jeffrey Wright is one of my favourite actors)
2046 (Almost any Wong Kar Wai film)
Diva
Any Luck Beeson film.
Infernal Affairs ( Any film with Tony Leung)
Who is the best actor you've seen in a Spike Lee film.
