#16: True Blood (2008-2014)
Another beloved vampire series, True Blood, was once king of the supernatural television realm. It was lauded for its storytelling — until the final seasons, anyway. A lot of fans became disenchanted by the show by season six because it no longer felt true to itself. Plot holes, inconsistencies, and ridiculous character developments made for a disappointing sixth and seventh season for many. Some would even say the last few seasons sucked.
