This Sleeper-Hit 5-Part Fantasy Sitcom Officially Needs To End With Season 6

So, while some shows get canned and never reach their potential, others might become repetitive, lose their spark, and could disappoint viewers altogether. And whether that's a result of a loyal fan base still racking up viewership, low production costs or the network's belief in a show's shelf life, some TV shows get a little bit more time on air than they deserve.
