I love this. It probably my favorite non-period (non-samurai) Kurosawa film. I don't know what people find boring about this film. I actually find myself wanting the movie to continue once it is over. It leaves me thinking, "what happens to the characters next," which could be a bad thing, but in the case of this film, it just means that I have grew attached to the characters.
In fact, the only Kurosawa film that I tried watching, but just found too boring was The Bad Sleep Well (but then again, I only saw a little over half of his films). I just could not follow what the hell was going on in that. I tried watching it twice, but I had to turn it off both times because I just lost track of what was going on. I think the major problem for me was that I got confused about who is who.
