Bah. Haven't seen vol. 2.
Vol. 1 was mildly amusing, but mostly because of that scene at the end where Uma's on the Jumbo headed from Okinawa to Japan. She's got her katana between her and the window (we saw that shot earlier), but the camera pulls back to show that whoever was sitting across the aisle in first class left his/her katana there while attending away-from-chair business.
So, on flights inside of Japan, are you allowed only one carry-on, and one katana?
best shot of the film.
