23. Babylon 5
Babylon 5 was groundbreaking in the way that it told a novelistic story on the small screen, with each episode telling one piece of a single puzzle that unfolded over five seasons.
J. Michael Straczynski’s brainchild also dealt with some heavy themes including ideas of war, peace, free will, religion and addiction, all wrapped up in an epic sci-fi drama.
The sheer depth and complexity of the narrative saw Babylon 5 gain huge cult status, and helped popularize effects-heavy TV projects while also harnessing the nascent power of the internet as a marketing tool.
