Ozu classic Late Spring easy to appreciate but hard to enjoy

Ozu's 1949 classic Late Spring has the Ozu qualities right from first frames - a domestic drama told and seen from the "tatami POV" - with the very low almost floor-level shots as the characters loom slightly above us, long shots down the hallways of the small apartment, and many establishment shots that give us a great and haunting sense of the beauty and the devastation in occupied Japan - many will note the bicycle riding scene when we see various English-language signage along the roadway, including Drink Coca-Cola. That said, it's a movie better to study than to enjoy. Yes, the plot is simple and beautiful and contains a surprising twist at the end (I won't give it away) - a young woman very devoted to her aging, scholarly father (and he very dependent on her) who believes she should never marry. Lurking beneath this placid surface - including about a 15 minute scene when father and daughter attend a Noh drama, spare me from another such cinematic 15 minutes please - there's a lot of sexual turbulence and undercurrents: the woman's health is not good because of the stress of her work during the way - never exactly specified or clarified - her attraction to her father's editorial assistant, and his to her, and her laughing dismissal that he is long engaged to a mutual acquaintance, her conversations w/ a divorced friend who's "modern" (her apartment is entirely western in decor) and perhaps "loose," and most of all the odd day she spends in Tokyo shopping with her father's colleague - divorced and remarried - and whom she accuses of being "filthy." She's a very upbeat young woman - might remind you of Poppy in British film Happy Go Lucky (?) - but there is much that's disturbing within her and in her background, and she enters into marriage with a lot of foreboding and doubt (not sure, but Ozu may have done a sequel - or he certainly could have). A very smart movie but even at its reasonable 1 hour 50 it seemed very long and slow, even for its time.
