Just one of the "hundreds" of Miike Takashi films, Mole Song is based on the manga series Mogura no Uta. Not knowing this before watching the movie, I was quite surprised. Most anime/manga adaptations I've watched lack any creative maturity, either in acting, script or direction. Mole Song tells the tale of an inept policeman who gets fired and is "promoted" to become an undercover mole and infiltrate a yakuza clan. From the opening scene though, this clearly is more than just a generic yakuza action movie. A balanced mix of comedy, action, and even the slightest touch of romance, Miike brings me back to the time of Happiness of the Katakuris but with a bit more flair and adequate pacing that some of his other films seem to lack (though I can't say I've seen more than 10% of them... there's so many!)
