Whether a series starts off with a bang or has rough beginnings, it's important to know when a show has simply run its course.
Here are 14 shows that probably should've been canceled this year, based on critic scores, viewership, and editorial opinion.
Warning: Some minor spoilers below.
"The Walking Dead" has lost so many main characters.
Gene Page/AMC
The zombie drama has been going strong since 2010, but eight years later it's suffering from recycled storylines , a loss of so many main characters, and a weird time jump that further complicated an already complicated show.
This season, the show's ratings have been down by 40% and, according to Variety, the show's ratings are as low as they've ever been .
"13 Reasons Why" has been deemed excessively graphic for a teen television show.
Netflix
This Netflix series has come under fire for its graphic portrayal of suicide, sexual assault, gun violence, and more. Although these are all issues people deal with, it's hard for many to understand why graphically depicting them is necessary .
Since the show's lead character Hannah Baker, played by Katherine Langford, likely won't be returning for a third season anyway, now could be the best time to end the series for good.
"Big Little Lies" mightve been best as a miniseries.
HBO
The HBO show did an excellent job of translating Liane Moriarty's book from page to screen. But just because it was a hit doesn't mean it should continue. With such a perfect season one finale, a second season gives the series the potential to tarnish just how great the first season was .
"Westworld" season three would be tricky to shoot.
HBO
HBO has a brief history of poorly executed second seasons of beloved shows ( "True Detective," anyone?) and "Westworld" suffered the same season two pains after its incredibly successful first season.
Plus, filming a new season may be tough. The filming location used in the show has sadly burned down as part of the destruction caused by the recent California fires.
Not everyone is sticking with "This Is Us."
NBC
According to Variety, the season three premiere had millions of fewer viewers than the season two premiere. Plus, the ratings have taken a slight dip.
Some viewers felt like after the mystery behind Jack's death was finally revealed, the show didn't need to keep going. The creator even told Entertainment Weekly that he wished he'd "slowed the spread" of Jack's death story and dragged it out for a bit longer.
"Now that we finally know how flawed-yet-sainted dad Jack Pearson (Milo Ventimiglia) perished on the NBC drama after a season and a half of dramatic throat-clearing and endless red-herring flashbacks recalling The. Best. Dad. Ever. Give this guy a halo and let’s call it a day," wrote Michael Starr for the New York Post .

"Madam Secretary" had a huge drop in viewers.
Sarah Shatz /CBS
According to Deadline, after the series' season three debut, the show's rating dipped quite a bit. The political drama has already seen lower numbers in terms of viewership , according to Variety.
"Legion" is even confusing to the cast.
FX
This bizarre series is loosely based on a Marvel comic, but the show can be incredibly confusing in every episode.
It's beautifully shot, but when even the cast doesn't understand what's going on in the show, it might be time for it to end.
"The Punisher" has been called excessively violent and boring.
Netflix
While Netflix is on its Marvel cancellation run , they might consider canceling "The Punisher."
According to many critics, the show is excessively violent, but somehow still a bit boring. Wired even called the Punisher the " least interesting character in his own show ."
Based on ratings, "The Simpsons" is long overdue for cancellation.
Fox
Although it's admirable how long this show's been on the air, it's not unreasonable to say that maybe it's time for it to come to an end . It's been on for 30 seasons and its ratings and viewers have been decreasing for years.

"Insatiable" has received backlash since the trailer first aired.
Netflix
The show about a woman who had her jaw wired shut so she could lose a ton of weight and exact revenge in her new "desirable" body was problematic enough in one season. In fact, it faced backlash before it even began .
Publications like Indie Wire have called the series a "disaster." Plus, some viewers aren't too pleased with the show either — there's a petition to get the series canceled and it already has over 120,000 signatures .
