Movie Review

Big Man Japan-

Well japanese people are truly odd. This movie is a mockumentary about a quiet odd guy who transforms into a giant super hero to battle other giant monsters.He is widely hated though. It is truly like nothing I've seen before.

[Ebert Review]

If you do watch it, the end is quite odd. Below is an interesting interpretation of it. DO NOT READ UNTIL YOU"VE WATCHED THE MOVIE! SPOILERS!
The Red baddie that had been beating up Daisato as Japan's fear of Red China. the red-white-and-blue clad "family" of characters who defeat the Red baddie symbolize America.

when the Americans "come to the rescue", the music that starts playing on the soundtrack is a parody of American patriotic music. the tall thin one is a caricature of Uncle Sam. he makes a stirring speech about "justice" and "peace", and then proceeds to (literally) tear the stuffing out of the Red baddie (suggesting China isn't as solid on the inside as it appears on the surface).

in the final scene before the credits, in spite of his misgivings, Daisato is taken forcefully (though gently) by the Americans as they all fly into the heavens together.

this is obviously an expression of Japanese ambivalence at depending upon America for its defense, and the fact that Japan's fate is largely determined by its close alliance to America (a closeness of relationship with another country that is unprecedented in the prior history of Japan).
