Critics devote their time to watching and reviewing shows, and sometimes the reviews are scathing.
Shows that could receive high praise for multiple seasons may fall apart at the end. Critics loved "Dexter" for years, but the series is one of the most despised in recent years. The "How I Met Your Mother" finale also disappointed critics and fans alike.
Here are nine of the worst finales according to critics.
"Dexter"

The serial killer's end as a lumberjack with a new identity wasn't favorable to many critics.
What critics said: "As the closing scene faded from my television screen, my reaction wasn't shock or sadness. It was anger....It's the kind of anger you feel after investing so much time into a show that you once loved, only to watch it fizzle out in the most unsatisfying of ways."— Vulture
"It's a feat for a finale to make you regret having watched a single moment of the series, but 'Remember The Monsters' made it look easy."— AV Club
"Seinfeld"

The polarizing "Seinfeld" finale ended with Jerry, George, Elaine, and Kramer in prison for being bad people.
What critics said: "It was such a terrible letdown...Still, future scholars will be poring over this last episode like the Dead Sea Scrolls. But, for now, I'd just like to say: It goes to prove money isn't everything in the writing of comedy."— Newsday
"The hype before the 'Seinfeld' farewell was one event the country should never go through again. The sitcom had its weakest season this year and should have gone off the air a year ago."— Orlando Sentinel
"Lost"

The "Lost" finale has been panned by fans and critics who felt that the flash-sideways plot took away from the island and the importance of the entire story.
What critics said: "So the sound you heard 'round about 10 Sunday night was thousands of non-romantics wishing for a time slip that would give them those two and a half hours and possibly six seasons back."— Los Angeles Times
"The ending felt contrived and disappointing, which was probably inevitable. After years of insane complication of plot and character, no ending could have 'explained' the show in a wholly satisfying way, and it might have been better not to try."— New York Times
