I don't really think this movie is "absurd" (as in absurdist) or surreal.
It's hilarious, but it's also a really dark and piercing commentary on Japanese nationalism and consumerism.
And yes, this will probably mess up the movie if you watch it before seeing the whole thing.
That is because they cut a big part of scene out. Bear with me, I have not seen the film yet so I could be dead wrong, but what I have heard is:
The Red Monster, 'the King of Terror' shows up. Now the thing looks hilariously bad but Big Man reacts like Satan's coked up Stepdad just stepped into the ring. He runs like crazy from the monster, which bears more than a passing resemblance to -Khaled Shiekh Muhammed-...
