Are you sure about that? I remember when home video became a thing. My family would gather around the TV with popcorn and soda and we watched together. We pushed all the way through. Pauses were, at most, just temporary breaks. We were gathered as a little tribe and we watched our movies in one sitting. We did not watch one half of an hour and then agree to watch the rest tomorrow. The movie was an event, a unit. When I watched VHS movies with my friends, we would watch all the way through (unless we decided to abandon a film altogether). Hell, even when I hung out at a video store with a friend and had every movie in the shop available with the equivalence of streaming (who library all at once, no late fees, no two-day rental), it was just understood that a film is a thing that you watch in one-sitting.
Are you sure you're not conflating what we've been able to do with what we actually do? Because I never go to a streaming service and think "Hey, I'm going to watch half a film tonight!"
But you still paused. Whether for a minute or a day, the flow of the film is still interrupted and the "contract", such as it is, is technically voided. In any case, watching them in "one sitting" (with temporary pauses) is your prerogative but can you sincerely speak to that being the way that everyone else watches films? It honestly describes how I try to watch films (hate leaving them unfinished if I can help it), but I don't think people are automatically wrong if they make the choice to resume at a later point.
And I would say that standing in ignorance or contempt of the general sociology of viewing is something a director does at her own risk.
A sociology of viewing that that happens to correlate with how you watch movies - you'll understand if I question its overall applicability to the average moviegoer. In any case, Scorsese was pushing 40 when home video dropped and pushing 80 when he made his first film for streaming so I think he's got enough awareness about how film-based technology changes in order to try to make it work for him wherever possible.
Or the audience will just say, "Err, a four-hour movie? Yeah, I'll pass."
And Roger Ebert is not quite right when he says that no great movie is never long enough. A great movie is great, in part, because it is NOT too long. You can only "leave them wanting more" if you don't exhaust the audience. Having sat through the Star Wars OT back-to-back in 70mm to get the original trilogy experience in one helping, I can vouch that committing one quarter of a day to watch Star Wars becomes the Bataan Death March at a certain point.
What exactly is the difference between "never long enough" and "not too long"?
In any case, at least three of the highest-grossing films ever made are over three hours in length and you can include an actual four-hour film like
Gone with the Wind if you factor in inflation. There is also a difference between spending four hours on one film and six-ish hours on three films (and as someone who has watched the first
eight Halloween films back-to-back in a theatre, the latter really doesn't seem like that big a deal).
I only quickly skimmed this thread and didn't read the bulk of it. So this is not about anything any of you may have said...
Personally I'm hesitant to watch a four hour long movie, especially if it's casting big Hollywood stars in what seems to be a serious historical event, that's not well known. Replace DiCaprio with someone who does more character acting like Michael Shannon and maybe, just maybe I'll watch it. And no I'm not a DiCaprio hater, I actually like him in entertainment type movies. I do like the subject matter of the film, I once seen a little known documentary about killings on a native American reservation, I wonder if this is the same story.
This is a curious distinction. I haven't exactly been DiCaprio's biggest fan in the past, but I wouldn't think that a star of his magnitude necessarily breaks the project purely by being involved.
