Narratively doesn't reach uncharted territory and definitely has some flaws in its plot progression but I'm just a sucker for these types of stories and it more or less hit the same notes for me as Shōwa Genroku Rakugo Shinjū did. Could have definitely benefited from developing its female characters though.
(Also glad it was Lee Sang-il that adapted it and not Takashi Yamazaki, or the majority of the film would have just been more conservative, manufactured Shōwa nostalgia.)
