Raumpatrouille: Die phantastischen Abenteuer des Raumschiffes Orion
(ARD, 1966)
This seminal German SF series (complete at only seven episodes) features groovy mod-club music, memorable sets (even in black-and-white), edgy interpersonal conflict and a winning marriage of ideas-based science fiction and action/adventure, undercut by an over-the-top, rather petulant Kirk-like lead character (McLane).
