This movie is not a cinematic masterpiece, but when you rent a Trauma movie it's generally common knowledge you're not getting "Godfather". Lloyd Kaufman has never claimed to be Coppila, and Troma has never claimed to produce art.
"Sgt. Kabukiman" is a true 'B' movie. It's poorly written, holds no great truth about the human condition, the fights seem staged, but it succeeds.
How?
It succeeds because it KNOWS it's a 'B' film, and not for one frame of celluloid does it take itself serious. We laugh at the characters because they are exaggerations of stereotypes.
Not to say there isn't some social commentary. I'd mention them, but I figure anyone who watches a Troma film looking for a profound statement about society shouldn't be watching a Troma film in the first place.
In the end, this movie is what you'd expect from Troma; a laugh with side helpings of sex and violence.
