A great story! I would recommend it to everyone, who was up for a romantic comedy...
The movie caught my attention from the first seconds...
It showed different couples, every time the guy was a foreigner (not a Japanese) and they were telling about the fun part of their lives...What wrong things do the foreigners do, which Japanese people find funny...
Inoe Maou, was brilliant as always...I love her English, and she tried to talk it quite a lot here :P
The guy, Toni, was chosen, very...how would I say...he was very eye catching, not the handsome guy you'd expect...but at the same time, sometimes so cute and lovable all the time.
The main idea of the movie (and I think of the manga too), that everyone is different, it doesn't matter are you Japanese or French, or American...Everybody's unique...and maybe our cultures are different, we're all people and get along, love, even marry :)

Overall...I loved the movie.
It's worth watching!
