"The existence of the 21st century itself is almost inconceivable. Ask any one who was around in 1999 how they felt about the incoming year 2000 and they'll be happy to tell you how surreal it all felt. Hell, they may even be nice enough to give you a non-perishable treat from their Y2K bomb shelter.

Sci-fi TV in the 21st century was both a friendly companion and a bold boundary pusher. Whether it took us to the heights of outer space, alternate universes, or even just around the neighborhood, science fiction stories truly enriched our pop culture landscape. What follows are our ranked choices for the best science fiction shows of the 21st century."
