Strangely, I've seen six Atsuko Maeda (the pop idol) films. The only one I liked her in was Hiroki's Kabukichô Love Hotel. She even got the money shot in that film and it was great. Here she's pouty and boring. In addition to across the board uninteresting performances the people in this film did most of their talking while acting eating. Gross.
Tamako graduated from a university in Tokyo, but she now lives with her father back in Kofu. Tamako doesn't help her father or tries to get a job. She spends her time just eating and sleeping throughout the four seasons of the year.
