Pretty Little Liars: Marion’s death
The show Pretty Little Liars contains so many plot holes that it would take less time to list all the gaps in the story.

Parks and Recreation: Who is filming?
Parks and Recreation uses a mockumentary style for its entire seven-season run without showing any reason for a film crew to follow the Pawnee Parks and Recreation Department employees. The Office handled its film crew reveal through Brian, the boom operator, which makes it better that The Office does not explain this element. The show abandoned mockumentary-style rules, according to co-creator Michael Schur, while they maintained some elements of mockumentary style through their use of one-on-one interviews, which provided them with humorous, brief methods to deliver exposition.
How I Met Your Mother: The mother
The main story of How I Met Your Mother ends after 208 episodes because it becomes a complete shaggy dog story. Viewers spent nine seasons searching for the identity of Ted's children's mother only to see her die shortly after her confirmation as the romantic interest whom Ted had been expected to end up with all along. The situation creates extreme frustration because it lacks logical coherence for multiple reasons since the show's writers established through their writing that Ted and Robin do not belong together as a couple.

The brain tumor, which Dr. Herman had, did not stop her from performing complex neurosurgical procedures.

That ’70s Show: Timeline inconsistencies
That ’70s Show might as well have been named That Whenever Show because the show contained numerous timeline inconsistencies throughout its entire duration.

The show produced five Christmas episodes throughout its four seasons, which created more confusing content for viewers. The second episode of the series shows Eric turning 17, but his 18th birthday celebration does not appear until season 6.
