Maybe the problem is not the film but the watcher?
Entertainment is required to be the best film ever?
Sorry, I've been meaning to respond to this, just haven't found the time to, but anyway, here goes:
1. Possibly. I'll give it a second watch... maybe.
2. For the best film ever... I would said yes entertainment is a requirement or a factor. Let's say for instance if a person was going to grade a film on some 100 point rubric with maybe 10 categories. For instance:
10 points - Script, dialogue
10 points - Cinematography/Beauty of image
10 points - Music/Sound
10 points - Legacy of the film in the film cannon i.e. classics, etc.
10 points - Pushing the boundaries of film in terms of technique and experimental ideas/language of film.
10 points - Acting
10 points - Behind the scenes stuff (think Apocalypse Now, etc)
10 points - Impact on other filmmakers
10 points - Personal impact on YOU and "reader response" type of thing. What emotions does it specific draw out on the individual watching the film or "me" - these are the bias points (ex - a film like Amelie and Breakfast at Tiffany's scores 10/10 for me on this.
And finally...
10 points - Entertainment.
So while entertaining isn't the only thing that matters, it is A thing that matters.
Now entertainment is subjective. For instance I love the driving scene in Solaris (Tarkovsky) as the story, mystery, etc has been set into motion and I can appreciate how it progresses toward the goal and gives ther viewer a sense of movement or journeying - there's a psychological entertainment to this. Similar to the opening scenes of 2001 or the landscapes in an Antonioni film, etc. With Jeanne Dielman, it felt manipulative and the purpose of a "scene" of watching her bathe herself for 5 minutes or bake a cake for 10 minutes was indulgent and not entertaining for me, even if from a exploratory/avante garde view it was to create a sense of routine or monotony in the viewer. I get it, but it's not something I necessarily feel the need to watch again or enjoyed at the time I was watching it.
That being said, it IS an interesting film, a daring film, and all of that, however in order for what I would consider to be the best film of all time, there should be some entertainment value. Moreover this vote seems like a vote to appeal to a post-woke, post-Trump, post-#metoo era, where there's an overemphasis on an element of the film, be it feminism, or to say that the best film of all time was directed by a woman. If a person advocates for that, it's perfectly fine, but to pretend those weren't criteria, seems to be denying the reality of how it got intersectional votes.
