Also, heavily biased towards the 20s-50s
Edit: more detail, 35/250 films are from the past 25 years, from 1998 to now. Less than 1/7 of films from over 1/5 of the entire history of film?
And then the consistant bias of impact to the industry vs actual filmic value... this isn't supposed to be a list of the 250 most impactful films... I've seen a few of these older films from the 20s or 30s. For sure, they were developing the language of film and are absolutely key to film history. But are you really going to say they stand up to films made in recent years with a fully mature vocabulary?
This is such a common occurrence on lists like this, they might as well be called "250 films you will probably watch in film studies class"
Another edit: I counted 42 films from the 25 year period from 1920-1945
