It’s odd to think that, once upon a time, a TV show set in space — one that declared, in its opening narration, as the cosmos being the “final frontier” — was considered the pop-cultural equivalent of an unwanted party-crasher. Yes, a concept like Star Trek was both of its time and clearly ahead of it; history has more than vindicated Gene Rodenberry’s notion of boldly going where no man had gone before. But given the number of top-notch shows set in the far reaches of the galaxy and that used genre for pulpy and profound purposes over the last 30 or so years, it seems crazy to think that one of the most groundbreaking SF series was a network pariah and a ratings dud. Today, there’s an entire cable network devoted to this kind of programming. You can’t turn on your TV/Roku/cut-cord viewing device without bumping into spaceships, alien invasion and wonky sci-fi food-for-thought.

#27: Agents of S.H.I.E.L.D.
While only sticklers tend to append the possessive sobriquet “Marvel’s” to this show’s title, it’s absolutely worth noting: After all, S.H.I.E.L.D.’s mission is to dance between the raindrops of the Marvel Cinematic Universe’s constant stream of big-screen blockbusters, reflecting changes to the status quo while still telling an engaging story about a team of super-spies in its own right. Ambitious action set pieces and likable performances from series leads Clark Gregg and Chloe Bennett ensure that it succeeds. STC
