The Irishman was my #10.
This is gonna sound really lame, but I'm very impressed by films that are very long but never get boring. I think that's just ridiculously hard to do. I've seen
The Irishman twice and I wasn't bored either time. I think I planned to watch it in two halves (the necessity of my schedule at the time, unfortunately), and either watched it all at once or watched way more of it than I was planning to, or just really really didn't want to stop. Something like that. The time flew by, is the point. And the idea that I'd watch something of that length
again, almost on a lark, is so wildly out of character for me that I had to put this high on my list, just to express the value from that sheer rarity.
I love the slow burn, I love how Marty kept nudging the slider in his mobster films away from the violence and more towards the personal, to the point where this film, on a per-minute basis, seems to contain almost none of the things you might think of when you first think of, say,
Goodfellas. It's like he weaned us off that stuff over several films and as many decades, and by the time you get to the end, the message is unmistakable. His condemnation of the lifestyle could not be more obvious, has been obvious for awhile, but enough people misread it that he had to issue this bucket of cold water, this cinematic slap to the face, to make it clear to anyone remotely capable of understanding, so that anyone who still didn't would be forever a lost cause.
