If you like science fiction type shows, Farscape is totally amazing!
Briefly, the main character is a United States astronaut who, while performing a maneuver in space, accidentally gets sucked into a wormhole that spits him out on the far side of the universe. There, he ends up on a living ship full of escaped alien prisoners.
The show follows what befalls the human astronaut and his adventures with his shipmates over the course of 4 seasons and a miniseries to wrap it all up, so the show doesn't leave you hanging at the end as some of the good ones do.
The Jim Henson Muppet people designed and ran many of the aliens, and you cannot tell they aren't real. It's amazing!
