Marco: Haha wo Tazunete Sanzenri, also known as How to Butcher a 52-episode Epic Series is a movie that trims down 1196 minutes of character development, magnificent settings, drama, sentimental bursts, emotions and empathy into 90 minutes of nothingness. The original series is a work of art that makes you feel what the characters are feeling, that makes you care for them and create emotional bonds. This movie lacks every single kind of emotions that made the Isao Takahata's 1976 production a masterpiece. Every hardship Marco goes through in this movie seems completely artificial, different from the series where the hardships are felt by you as much as they are by Marco.
Don't waste your time watching this. Watch the original series, one of the masterpieces of Isao Takahata's career, along with Heidi and Anne of Green Gables. They're capable of making you a better person.
