Possibly interesting fact? If you search imdb for features with 600+ votes from 1920-1924, the highest user ratings belong to The Kid (8.4), Safety Last! (8.3), Sherlock jr (8.3) and then, in a tie with The Cabinet of Dr Caligari at 8.1... this film. Well, I thought that was interesting since I'd never heard of it before this week. I don't think it's quite in the league of those other films, but it is very good.
