Zebraman is definitely one of these head-scratchers. Ostensibly a superhero film, it is Takashi Miike taking on a genre of Japanese television superheroes that flourished during the 1960s/70s with series like Ultraman (1966-7) and in particular Kamen Rider (1971-6), the show that seems to have influenced this with its motorcycle-riding superhero fighting rubbery aliens. You get the initial impression that Miike set out to spoof the genre an earlier scene from the tv series shows the amusing idea of a Kamer Rider-like hero fighting off Sadako from Ring (1998) and sequels.
From the premise milquetoast schoolteacher puts on a self-made costume from his favourite tv series and goes out to fight crime you get the impression that Zebraman is prefiguring the superhero-with-no-powers spate of usually comedic films that came along a few years later with the likes of Special (2006), Defendor (2009), Griff the Invisible (2010), Kick-Ass (2010) and Super (2010). The head-scratcher then comes that despite setting the film up as a parody of the 1970s Japanese tv superhero and/or a variant on the superhero-with-no-powers comedy, Miike does none of these things. In an entirely ill-explained twist, soon after putting on the costume, Sho Aikawa, unrecognisable as the detective protagonist from Miikes Dead or Alive (1999) and sequels, gains the actual powers of his fictional tv counterpart and starts kicking alien monster butt. (How he gets his powers and how everything that happens seems to have been predicted by the scripts for the tv series, which would appear to be written by aliens that crashlanded on Earth in the 1970s, comes with an annoying vagueness of explanation). There seems little discernible spoofery in these scenes mostly the film seems to be playing its take on the 1970s tv superhero straight, while the ironic contrast between the image of the superhero and the grim reality that films like Defendor, Super et al play on is quickly forgotten apart from a single early scene where Sho Aikawa tears the seams in his costume as he tries to do poses in it.
Zebraman feels like it needed more of the wacky gonzo approach of Miikes subsequent YatterMan, which was based on an actual superhero series from the 1970s rather than a made-up one as here. With no discernible comedic or tongue-in-cheek tone, all that that leaves one with is what seems to be no more than a straightforward homage to the 1970s Japanese tv superhero. The problem with this is that Zebraman is produced on a low-budget. Most superhero films gain their strength from having epic-sized dust-ups between superheroes and villains or monsters. I kept expecting Zebraman to emerge as something akin to Big Man Japan (2007) and its wackily absurd take on the genre. Zebraman, by contrast, never seems to leave the backstreets of a few city blocks. All that Miike offers up in this department are a few superheroic battles with the alien blob creatures that feature some very weak CGI.
