The TV landscape has been hit-or-miss lately, and not just in the storytelling department. There have been horrible star exits, delayed show plots, the loss of television institutions, seasons of popular shows that fizzled and exploitation-for-entertainment, creating a truly uneven and disappointing TV season.

TVLine chronicles the lackluster parts of this TV season in their countdown of “TV’s 20 Biggest Disappointments of 2011.” Some major disappointments include the axing of “All My Children” and “One Life to Live,” disgusting and horrific shows such as “Toddlers and Tiaras,” the not-too-great finales of “The Killing,” “Desperate Housewives” and “Smallville” and, of course, the worst thing that happened to television this year–the unleashing of crazy Charlie Sheen once he was fired from “Two and a Half Men.”

My personal “favorite” disappointments include Sheen running amok, “Toddlers and Tiaras” (I really hate that show), the terrible Season Nine of “Project Runway” and not seeing Clark Kent get fully decked out in his Superman outfit.

You can view the entire list at TVLine. Which disappointment on the list were you most disappointed by? What other disappointments weren’t on the list that should have been? (“Pan Am,” anyone? The cancellation of “The Playboy Club” and the “outrage” over the show?) Give your opinions in the comments section below.
