I though Tokyo Dogs is a crime drama, but after watching I've definately changed my mind! It's comedy! There was action, but too little. There weren't any tension thanks to lovely Sou's mother and her life problems with tamagotchi or something else...
Sou and Maruo make great detective team, though both have got specific sense of humor. I don't seep them, but they are funny.
To sum up, the drama isn't the best production, but it can be watched.
