The X-Files (1993-2002)
Finally got around to finishing the series. People say the last couple seasons were the worst but I don't find that to be the case. Were they bland? Yes but in no way did they approach the worst. Look no further than War of the Coprophages for that. The show really went down the stinker when Carter left for that brief period of time. Whether it ever fully recovered from that is questionable.
