10 Best Sci-Fi TV Shows You Can Watch Online For FREE
1. The Prisoner
Finally, the oldest entry on this list is considered one of the greatest British TV shows ever made.
Lasting only a single season of 17 episodes, The Prisoner is about an unnamed British intelligence agent who is abducted and imprisoned in a mysterious coastal village, where his captors try to find out why he resigned from his job. The spy, played by Patrick McGoohan, is known only as Number Six, the name given to him by his captors. The series follows his efforts to try and escape from the village while also discovering more about those are holding him, including the mysterious Number One.
The show generated much controversy on its release in 1967, especially after a highly controversial and ambiguous ending , but it continues to top TV polls today. It also has countless references in various popular culture, with Big Finish productions making an audio recreation, an episode of The Simpson featuring McGoohan and even a song based on the show by Iron Maiden.
