8 shows so bad they're good, from Riverdale to Mighty Morphin Power Rangers

Screen Rant has put together a list of eight TV series that are delightfully bad, in the best possible way. The argument? Not every show needs to be prestige television. Sometimes, a campy romp is exactly what you need.

Among the picks is ABC's "Once Upon a Time," which Screen Rant calls a fever dream of storytelling. The show had a live-action Disney feel, but its plots were famously convoluted, including a family tree that would put "Game of Thrones" to shame.

"Pretty Little Liars" starts strong but eventually gets derailed by continuity errors, toxic relationships and an evil twin with a British accent. Screen Rant points out that a feud over Lady Gaga Halloween costumes is a masterclass in camp.

Ryan Murphy and Brad Falchuk's "American Horror Story" makes the list for losing focus and adding unfounded twists and tonally dissonant musical interludes. Scream Queens, another Murphy/Falchuk/Brennan project, is also included for its dark humor that didn't always land.

"Teen Wolf" gets a nod, with Screen Rant noting its dated technology and low CGI standards, but arguing that Dylan O'Brien's Stiles Stilinski is always entertaining. The show won plenty of Teen Choice Awards, proving it succeeded in the circles it was designed for.

"Mighty Morphin Power Rangers" is described as a show held together with hope and a dream. Its first season relied heavily on stock footage from the Japanese Super Sentai series, and props were frequently reused. 33 years and 20 spinoffs later, it's an underdog story.

"Glee" is a decade-defining series, Screen Rant says, though its representation is flawed in hindsight. And then there's "Riverdale." The show started as a gritty murder mystery inspired by Archie comics and somehow turned into a genre-defying fusion of Gothic horror, high fantasy and Broadway musicals. Screen Rant calls it the most unhinged show ever made.

Riverdale's Rotten Tomatoes scores tell the story. Season 1 had an 88% critics score and 79% audience score. By Season 6, the critics score had dropped to 67% and the audience score to 38%.

Screen Rant argues that in an age where most shows are kept on short leashes, there is something to be said for a show that unapologetically embraced inanity and kept viewers enthralled for 20-plus episodes at a time.
