Andrei Tartovsky vs Woody Allen.
Here's how this works; I normally pull what I take to be the 10 best films for a movie person (actor, director, screenwriter, etc), and compare them to someone else's best 10. To the extent that I am familiar with the works, I use my own opinion; when I don't know about specific films, I use collected critical commentary (I read a LOT.)
In this case I have to drop down to 9 films rather than the customary 10, because while Tartovsky directed 11 films, I only have solid commentary on 9 of them. So I am throwing out one of Woody's middling efforts (ie, what I consider the 5th best of his top ten), Husbands and Wives, and using the remaining nine for comparison.
Now, the goal is to try to match up individual films, or for balancing's sake, 2 films each for the subjects that in my opinion are of comparable artistic value. At the end, I am usually left with a small set of films for each artist, and it is generally clear that one's "leftovers" are of higher quality than the other's.
Yes, it's crazy, but it just might work!
So Andrei Rublev and Annie Hall are of comparable value, and get removed.
Then Manhattan, and Solaris
Hannah and her Sisters, and The Mirror
Ivanovo Detstvo, and Love and Death
Sleeper, and Stalker
The Sacrifice, and Zelig
And that's it. For my money, Woody's still got two good movies left, Deconstructing Harry and Manhattan Murder Mystery, and one great one, Crimes and Misdemeanors
Rublev's only got his three weakest films remaining, Nostalghia, Steamroller and the Violin, and Tempo Di Viaggio. From what I can glean, none of these films are bad, but there's nothing especially exceptional about any of them.
So Rublev gets a sentimental nod for having "Steamroller" in one of his titles, but this system prefers Woody.
