Cartoon Network’s Samurai Jack, the brainchild of Genndy Tartakovsky, is usually filed under “samurai fantasy.” Yet dig beneath the bamboo leaves and ink-washed skies and you’ll uncover a show that adores rockets, alien star-yachts and bug-eyed killer drones. Across its five seasons the cult series repeatedly hurls its stoic hero into orbit, proving that space-sci-fi can flourish beside Zen minimalism without a single creak in tone.
