Yebbutt if you're a cinema sophisticate like wot I am, you'd appreciate such things.
That said, have you seen Woody Allan's "Interiors"? 'kinell, that's dull ! Or the first 40 minutes is at any rate, I can't comment on the rest. He was trying to be Bergman rather than doing the funny stuff. Apparently it's a masterpiece !
And even"Ran", the great Kurosawa's last film isn't high on my list. Obviously it looks stunning, as you'd expect from the Great Man, but I didn't find it all that engaging, though the central performance is powerful. That said King Lear, which it's based on isn't my favourite play either, as the story is so bleak,
Some so-say action films can be a crashing bore too - we walked out of Gemini man, and I must admit I found the first Hobbit film very tedious too, even though both have plenty of action - unlike either version Solaris.
My favourite film of all time is "Two Lane Blacktop" - a slow paced, yet to me, compelling road movie. Opinion is split between cinematic masterpiece (my own view) and dull plod/nothing happens (which whilst wrong isn't entirely silly either)
