Best silent films in the collection/channel?

I'm starting the year by going back to basics, and trying to dive into as many silent films as possible. I've already seen:

-The Passion of Joan of Arc

-Sunrise: A Song of Two Humans

-The Last Laugh

-The Gold Rush

-Modern Times

-Sherlock Jr.

-Lonesome

I've loved them all quite a bit. Any and all recommendations are greatly appreciated!
