Some films are horrible - that's the point. You're not supposed to enjoy them, you're supposed to be scared, disgusted, and even offended by them. That doesn't mean that they are bad films though. Some of them are, but there are some films that you should see at least once, if only once.
After the news that hundreds of people walked out of Lars von Trier's The House That Jack Built at Cannes Film Festival, here are some films that you should make the effort to sit through even once, even if it is an effort.
For the record, this list doesn't include films like A Serbian Film, and The Human Centipede because even though they are horrible and repulsive, they are just not very good.
First up, Requiem For A Dream.
It's a psychological drama directed by Darren Aronofsky, who also directed Black Swan and The Wrestler, and it tells a gruesome and gritty story of addiction.
To be quite honest, it's worth watching simply for Clint Mansell's score, but it was also critically acclaimed and led to an Oscar nomination for Ellen Burstyn for her performance.
Next up, is the 2011 film (based on a novel of the same name) We Need To Talk About Kevin.
More relevant than it has ever been, given the amount of problems in the USA just now, the film tells the story of a mother whose son committed a brutal massacre in his school.
It's a tough watch and includes some particularly horrible scenes, but it's well told and well shot. As with Requiem, it also won critical acclaim and was recognised on the awards circuit.

Hey, if you're massively worried about a nuclear holocaust (and why wouldn't you be?) why not consider watching Threads just the once.
When it came out in 1984 on the TV it shocked the public by focusing on what would happen in the immediate aftermath of a nuclear strike on the city of Sheffield. It's low budget, and it probably hasn't aged well in the past few years, but that just makes it even more of a 'see it, if only once' type of film.
Finally, it's another work by that man Lars von Trier.
Antichrist starred Willem Dafoe and Charlotte Gainsbourg and told the story of the relationship between a mother and child, a husband and wife, and even had a talking fox.
There's nothing cute about this film though, and it provides one of modern cinema's most horrific moments towards the end.
