I can sympathize for your audience, but not sight unseen. I have watched and reviewed Norte: The End to History as you recall in Filmleaf as part of the 2013 NYFF. That's worlds away from the wonderful Edward Yang. I am a big fan of Yang, & described rewatching A Brighter Summer Day at Criterion in my Feb.-Mar. 2016 NY Movie Journal. I reviewed it at more length in 2012.

Most blockbusters are too long. Nolan's innovative (and superb) 106-minute-long Dunkirk is an admirable exception. But it's obvious 4 hrs. 20 mins. is a tough sell even for art houses.What would you do? You just have to promote it as a video or a mini-series. Olivier Assayas' Carlos the 5-hour miniseries (which I saw in a virtually non-stop NYFF screening at the Walter Reade) got some theatrical showings (at the Quad I think, after a blizzard). Edward Yang's movies are short for what they contain. Diaz's are long before you've watched 15 minutes of them because they're deadly dull, or so it seems: I've only watched the one, but obviously I'm not eager to delve deeper.
