I honestly don't understand what you mean when you say, there can be one greatest movie. Literally Captain Quint's post just said the opposite but you said you agree with his post, yet you seem to be pushing back on those who say there isn't just one greatest movie. I really don't understand how you're parsing this. Are you misreading us? Are we misreading you?
Is this some Abbot and Costello routine? How do we just keep getting shuffled right back to the start of this conversation?
Where have I said 'there can be one greatest movie'? I have repeatedly, repeatedly, repeatedly stated that the notion of there being one movie that is objectively better than all is a completely impossible argument to prove.
Instead what I have said is it is pointless to endlessly talk about how there is no such thing as a greatest movie "because it's all just a matter of opinion". But just because something can't be proved, this doesn't mean a valuable conversation can't be had in understanding WHY people BELIEVE certain movies are better than others. WHY some people BELIEVE one movie can be the best of all.
WHY means we are learning about how others think about film, and by proxy, how they think about all sorts of other different things. That matters.
BELIEVE means its a belief. We don't need to prove a belief. Art is an article of faith, in many ways not completely removed from religion. Faith can be more important than proof. You can have a conversation about what you think God is without inviting him to the dinner table. Same thing with movies.
So I have never, not once, in my entire life, ever said that there "is one greatest movie". All there can be is one greatest movie for an individual, based on their feelings and knowledge and life experience, and that can be absolutely anything. It can be Blues Clues Licks His Balls for all I care. What matters is do they have anything of interest to say about it.
In this instance Spielberg is saying it's the Godfather for him. And maybe in other instances he has said something else. Which you are allowed do. These stupid rankings aren't a stagnant pool, because ultimately Speilberg's conclusion here isn't of much interest. It's how he explains his position, on that day, in that mood, in that situation that matters. Who cares if he's said It's a Wonderful Life is the best movie on other occassions. I'd like to hear his reason for why both might be considered, without being blinded by the inherent contradiction that there can't be two greatest movies. Because WHO CARES what the greatest movie of all time is. We have already established it can never be proven, so let's not get hung up on something we already all agree on anyways. It just ends up being distraction from the actual conversation of what makes it possible that someone would think the answer to the question is The Godfather (just as Boy Wondeur rightfully pointed out a few pages back)
As for me agreeing with Quint's quote, that is just an interesting philosophy of how to look at all art. It's the idea of getting to a zen like state where we no longer differentiate between what films are good or bad, better or best. Where we just understand it as a lineage of human expression through the ages. And this is actually the philosophy that has guided my last twenty years of watching films, and why I have also repeatedly claimed over the years that (much like Mark claimed) there isn't such thing as a bad movie. They all have something to offer. What matters is that people made them. Who gives a **** if they are technically good. Worrying about quality is a waste of breath when you would prefer to look at the whole history of cinema (or painting, or music, or books) holistically instead of individually. And I'm more interested in looking at it that way.
But just because this general philosophy lines up with mine, doesn't mean I somehow can't play along with these silly games of 'what's best'. Because, as I stated above, and all over this forum for the past few years, we can still get things of value from the discussion no matter what movie we end up talking about. I just don't put any particular weight on who is right, or who is wrong, or who made a masterpiece, or who made dog shit. I'm here for the conversation. And while, yes, I too choose sides (I think 2001 is the greatest, I think Babydriver is the worst), I only do so as a provocation to talk about the things I like in movies, and the things I don't like so much, and then see if people agree or say my taste is dog shit. Either way, I don't care if people agree or disagree. I just care that they say something worth starting a conversation or a debate over. Because that's how we learn. And learning is good.
Basically the only thing I don't see the point in, is constantly going back to the drawing board with "but there can't be a greatest movie", or "why bother having this conversation since we can't prove who is right", because these hot takes just lead to a road of mostly nothingness. Because if we take these points as gospel (and, admittedly, they probably are), why even bother talking at all? We've already decided anything anyone says is pointlessly 'subjective' or 'personal' and 'can't be proved'. Where can you possibly go from there? You're lost if you get hung up on these sorts of technicalities, instead of just looking and listening to what the person is saying about what they like, or don't like, or think is the greatest of all time.
