15 Underrated Sci-Fi TV Shows You Should Be Streaming Now
6. Firefly
Firefly is Joss Whedon's futuristic vision of a rag-tag team of space smugglers struggling to make a living in a cruel and violent post-war future.
When the crew of Serenity decide to take on some passengers to earn a few extra coins, they become the unwilling protectors of a brilliant doctor and his mysterious sister River.
The ensemble cast headed up by Nathan Fillion, Gina Torres and Alan Tudyk are endlessly watchable and Joss Whedon's sci-fi/western world (which clearly owes a debt to the original Star Wars trilogy) is perfectly realised.
Firefly is fun, witty, action-packed and suspenseful but it was cancelled early due to low ratings. Its single season has since become a cult favourite, earning a feature film follow-up in the process.
