Every year has its good movies and bad movies, but it takes a special quality to be both good and bad at the same time.
Sure, there are plenty of dumb-on-purpose movies, like "Black Dynamite." Or campy movies, like "Face/Off." And there are soulless attempts to be purposefully trashy, like the "Sharknado" series.
This list isn't about those. These are about the movies that were made sincerely, yet fail on every level — and are hilarious as a result.
Here are 18 movies that are so bad, they're good.
"The Room" (2003)

Directed, starring, written by, and produced by Tommy Wiseau, the movie is a simple tale of a man scorned by his wife who cheats on his best friend.
It's astonishingly bad. "The Room" is considered one of the worst movies ever made because of the sheer incompetence in front of and behind the camera. Now a cult classic, the movie plays at midnight screenings around the country, sometimes with Wiseau himself — now insisting he was in on the joke — there for the Q&A.
The legend around "The Room" has grown so great that "The Disaster Artist," a movie starring and directed by James Franco, which is based on a behind-the-scenes book, was released last year. It's up for an adapted screenplay Oscar.
"Battlefield Earth" (2000)

"Battlefield Earth" was widely ridiculed upon its release and flopped at the box office, but eventually became a cult classic.
It's a sci-fi epic starring and produced by John Travolta, who adapted the book from a novel by Scientology founder L. Ron Hubbard. It's about humans who revolt against an ancient empire of alien rule.
As you can imagine, it's filled with awkward dialogue, nonsensical plots, wooden acting, and poor lighting.
"'Battlefield Earth' is like taking a bus trip with someone who has needed a bath for a long time. It's not merely bad; it's unpleasant in a hostile way,"Roger Ebert wrote upon the movie's release.
"Plan 9 from Outer Space" (1959)

Before "The Room,""Plan 9 from Outer Space" frequently held the title of the best bad movie of all time. It's a low-budget sci-fi flick from 1959 made by exploitation master Ed Wood, about aliens who try to stop humans from developing a weapon that would destroy the universe.
With a big budget and a smart script, the movie may have worked. It has neither.
