Interesting film as in this moment Science Fiction/Fantasy had matured, through the New Wave (/New Worlds, alluded to herein by Mike) and then others in the US. (Dangerous Visions, etc)
Also, Michael trips over his own wires when he Marcuses himself off, at the end, sotto voce... Censorship is, in fact, eternally Rotten... And the 'restructuring' he advocates is the same now dated method which has hatched so many ills throughout its long brooding tenure...sincerely, Gloomrod...
