I think "Lost" fits into that category. Watched the first episode, and was already wondering who came up with that ridiculous plot. I think I got 3-4 episodes in before I quit. For a remote island, it sure had a lot of secret vaults/other groups/wires/etc. hanging around. And the final episode, were they supposed to all be dead in purgatory or something? Dumb.
Though I enjoyed the first four seasons or so, "The Walking Dead" obviously asks people to suspend a huge amount of belief (like, ALL belief). At least "28 Days Later" had zombies that were essentially people with rabies who could die of hunger eventually. TWD has half-torso skeletons grabbing people. Some are so slow that a single person can take out 30 without help, but then how did so many characters bite the dust? You can literally walk away from them without being caught. Ever since they found Alexandria the series has been massively stupid.
