Any baby boomers who wander into “Headspace” might be forgiven their momentary panic as they are suddenly acid-flashed back to the psychedelic mediocrity of their youth. Jethro Senger’s attempt to capture the global mindset of ravers, largely through visual mimicry — kaleidoscopes, anyone? — is at best a mixed bag of old tricks. At worst, it imagines techno music, that love-child of human and machine, as a flock of digital doves dropping bombs that mushroom into pink hearts. Pic, opening today March 28 at Gotham’s Two Boots Pioneer, makes underground music docus like “Maestro” look positively scholarly.
Traveling the world to discover that one rave is pretty much like any other, Senger offers variation only in the form of low-tech special-effects — trancy dancers variously synched to the beat in blur-image, slow-mo or night-vision green. Pic is not without humor: Two cars linked by cell phone futilely circle each other all night in search of an elusive bash, but the gag quickly palls. “Headspace” takes no moral stance — Ecstasy will either save the world or fry the brain (cut to a flaming cerebellum, sans eggs). Senger welcomes party animals and paranoid doomsayers alike.
