I've expected this to be better than it ended up being, as the story seemed intriguing and the mange on which this film was based on is quite popular. However, the result was rather boring. The story did had some originality at first and it had it's funny moments, mainly due to the leading actor who was really good portraying a man who was turned into a teenager again. However, most of the events of this film were just the same ones you'll probably find in any other Japanese manga school movie: the festival, the school fair, the trip etc. I would rather had the story focusing more on the main character and his journey to change himself and become a better future self. Finally, the love story was okay, had it's twists and surprises, but the two actors didn't have much chemistry to work with. So, 4 out of 10.
