The title of this movie doesn't make a lot of sense, until you see it in operation, because it's the sound that a retarded young man makes while he's operating his imaginary trolley, which is what he does all day. And he is just one of many odd characters in this surreal at times, tragic tale of a group of slum-dwellers in Japan.There are two drunks who trade wives, there's a man with aspirations to be a architect, and his young son who he sends out to beg for food. There's a wise old man who seems to be the pillar of sanity within all that goes on around him, and there's a businessman with some severe nervous tics that has a wife that treats him (and everyone else) like dirt.There's no particular plot to this, really, it's a bunch of stories that drift back forth between each other, sometimes funny, sometimes tragic. All in all I thought it worked pretty well, I had been dying to see this for a long time just based on its description. I was not in the least disappointed, and I'd definitely recommend this. 9 out of 10.
