I hope so. I have heard great things about Lloyd, but have only seen Safety Last! Other silent films by him weren't available here. 
The focus on Keaton and Chaplin puts similarly great comedians (I'm sure there were some more in the silent era) on a side-track. Some Academics seem to accept only a certain number of greatness, or if two or three people get aknowledeged, they tend to believe the important work has been done. Now with the DVDs a wider public gets to also decide the truth of it.
