It's no wonder that Sliders was a hit with sci-fi fans in the late '90s. The show is smart and its premise unique, plus it adds in just the right level of comedy to lighten the mood at appropriate times without resorting to corniness. It manages to toe the line between entertaining and challenging viewers to think critically about how the world has evolved over time, thanks to storylines that adjust history to present images of how the world would look if important events were altered, like the outcomes of wars or the invention of modern medicine.

This is good news for viewers who want something besides a predictable, one-dimensional story, but Sliders does require some background experience and knowledge for the show's format and somewhat fragmented storyline to make sense. For this reason, it's best suited for teens and adults, and those who watch will be treated to a thought-provoking journey through versions of what might have been our world had history played out differently.
