All of this ‘new old school’ junk like Diebuster and Tengen Toppa Gurren-Lagann have actually made me go back and check out the real old stuff, most of which is thankfully discounted these days. The entirety of Giant Robo, for example, can be had for eighteen bucks- six glorious episodes of dark, retro-style science fiction that plays out like a comprehensible version of Big O, in a way. Not to mention it coming with the Ginrei Special that refreshingly spoofs itself.
Then there’s the Gunbuster re-release. Nuff said?
