"Almost all of the original stars were gone and no one was watching."
1. Dexter
Showtime
"It could have ended at season four and gone down as a true classic. I still love it, but it really tarnished itself."
"I still like the other seasons, but it definitely peaked at four."
2. Glee
Fox
"Should have stopped when they graduated."
"Absolutely. Everything post-graduation was a train wreck."
3. The Office
NBC
"It should have ended when Michael left."
"When Michael gets on the plane in The Office I stop at that point. It’s the last episode in my world, and I rewatch the series about once a year."
4. Shameless
Showtime
6. The Vampire Diaries
The CW
"It became unwatchable to me somewhere around season four or five if I remember correctly. It was the constant 'I’m gonna have to kill you now' to friends again back and forth that did me in. Like I get it's a show but it was sooo annoying to me."
7. Once Upon a Time
ABC
8. X-Files
Fox
"The post-Mulder seasons had some decent episodes, but it really should have wrapped up when he left."
9. Supernatural
The CW
"It turned into a travesty. I couldn’t finish the final season. A lot of people say it should have ended after Dean came back and lived a happy life. That would have been a fine finale. I would have been fine with Sam still coming back and having 2-3 seasons to wrap everything up. But once the mother came back I was out."
10. Weeds
Showtime
"It got pretty dumb after the first couple of seasons."
"Yeah, it really went off the rails in the later ones."
11. The Walking Dead
AMC
"The show pretty much peaked after four seasons, it really went downhill in season seven with the introduction of Neagen. By the end of season 11 almost all of the original stars were gone and no one was watching."
12. Bones
Fox
"Although I did enjoy the last season, I felt eventually story lines became a bit too unrealistic in later seasons and had too much drama that simply wasn't entertaining."
13. Castle
ABC
"It should have stopped entirely at seven, and should have had some serious changes to writing and storylines as early as four."
16. Californication
Showtime
"As much as I love that show, the last season was weird and felt like they fired the original good writers and brought in a bunch of generic ones to recycle the plot of the show."
17. The 100
The CW
"It should’ve ended with season five. Everything that came after it effectively ruined every single good memory of the show."
18. Smallville
The CW
"I swear, this is my favorite show of all time, but they should have ended it either at season five or seven. They dragged it on for ten seasons due to its popularity, but when series creators Miles Millar and Alfred Gough left the show changed completely. The whole vibe was different. They introduced Lois Lane in season four. Four! And dragged it out for six more years!"
19. Sabrina the Teenage Witch
ABC
"That show jumped the rails hard after season four, switching from ABC to CBS and removing the two aunts."
