(Over)simplifying it, all Japanese movies could be divided into four categories:

1) The GREAT ones, stuff like the "Kazoku wa Tsurai yo!" trilogy, or "Umimachi Diary", or many many others, all magnificent examples of what makes Japanese culture so unique and fascinating

2) The SILLY ones, titles like "The World Sinks Except Japan" or "Oppai Volleyball" and many others; in a decent portion of these, the silliness is actually pretty funny, making such movies still enjoyable

3) The YAWNFESTS, or what I tend to refer to as "Victims of the nefarious influence of French 'Nouvelle Vague' and 'Cahiers du Cinéma'..."; pompous and artsy, painfully slow, with horribly thin (or even non-existing!) plots, unappealing dialogues etc.

4) All those which cannot fit in any of the previous (hey, I did warn you I was oversimplifying it! ^___^;;;.....)

Unfortunately, this "Bread & Bus Etc." fits in the third category. It took me FOUR DAYS to finish it, because I literally couldn't stand watching more than half an hour of it in one go (and usually my eyelids would start feeling horribly heavy already after ten or fifteen minutes...>____<).
The whole plot could fit on the back of a postage stamp, and if it had been done as a short movie (like, five minutes, tops) it might have been okay. But at close to two hours, it's almost unbearable.
Too bad, because Fukagawa Mai (the reason why I've watched it!) possesses a pretty nice acting talent. But it just couldn't shine in this yawnfest, alas.
