Karate Robo Zaborgar presented me with the sort of soul-searching conflict that often plagues those of us who worry about the higher philosophical questions in life. On the one hand, it was a presumably loving spoof of one of my favorite genres — the old “tokusatsu” superhero shows of the 1970s, with their karate cyborgs, fringed jeans, motorcycle helmets, random explosions in rock quarries, and theme songs dominated by jazzy trumpets. On the other hand, I watched a similar movie last year — Takashi Miike’s Yatterman — and still consider it one of the worst, most unenjoyable movies I’ve seen in the better part of a decade. My bottomless disdain for Yatterman comes despite the fact that I generally like Miike as a director. Karate Robo Zaborgar, by contrast, was directed by Noboru Iguchi, a director who has yet to make a movie I didn’t dislike. His stock in trade is slapstick splatter send-ups of popular Japanese genres, but done with such juvenile laziness and awkward, ill-realized timing that what should have been outrageous comes across merely as tedious.
