The movie is a bit boring at times, especially at the beginning and the time travel thing isn't done in a very compelling way either. The random rules people have to adhere to in order to visit the past just seem like excuses so the production could stay within its budget. It could have been done more creatively. There are some charming and emotional human interactions and stories in the various subplots, but not all of them are intriguing and it's a bit far fetched that it all takes place with the cafe as the center. It's almost like a theater play with different life lessons. So it kind of swings between nice and "could be better", but ultimately I did like it because like most japanese movies it's very wholesome and a welcome escape from the ugliness of modern western "culture".
