22. 'Space: 1999' (1975-1977)

When Star Trek became a belated hit in syndication, smart producers set out to capitalize on the "space is the place" trend — which is how "Supermarionation" mavens Gerry and Sylvia Anderson ended up making this stylish, high-toned live-action series. Their highly Trek-esque plots saw Earth’s human-inhabited moon hurtling through the universe after an explosion and getting embroiled in interplanetary conflicts. Today, fans love the show for its snazzy disco uniforms and elaborate spaceship models — both of which resemble a certain blockbuster motion picture that was still in production at the time. If only the show had stayed on the air just one year longer, it could've ridden that Star Wars wave to bigger glory. NM
