If another director was attached to this film, I'd say it was pretty good. Considering that the supremely unconventional Takashi Miike helmed it, it's fairly disappointing. To be sure, "Rainy Dog" was an interesting gangster tale. Nothing about it had that Miike extreme flair, though. There was a lot of rain, so if that soothes your nerves, this film would definitely work for that, otherwise, there really isn't much to distinguish it from other crime/mob fare. See if you're a Miike completionist like me, otherwise skip it.
