Simple enough to be explained by the following example:

I'll start: What is the most gruesome movie you've seen?
"which film is the worst ever with all categories included?"
Fantasy Mission Force is the worst I watched, technically, but it was still pretty enjoyable.
"Nominally set during World War II, the film begins with a Japanese attack on an Allied military camp, which a map reveals to be somewhere in Canada. After four Allied Generals, including one who introduces himself as Abraham Lincoln, are taken hostage by the Japanese troops, Lieutenant Don Wen (Jimmy Wang Yu) is called in to organize a rescue effort (rejected candidates for the job include Roger Moore's James Bond, Snake Plissken, Rocky Balboa and Karl Maka from the Hong Kong film Aces Go Places).
With promises of a huge reward, Don Wen rounds up a group of misfits for the job, which includes two kilt-wearing soldiers[more than just kilts, those two Asians were completely attired as Scots from what I can recall. Really], a hobo (Old Sun), a supposed escape artist (Greased Lightning), con artist Billy, and the femme fatale Lily (Brigitte Lin), who sports knee-high red leather boots and a bazooka. En route to the Japanese base where the kidnapped Generals are being held (apparently located in Luxembourg according to the film), the group encounters two small time crooks, Sammy and Emily (Jackie Chan and Ling Chang), who follow them in hope that they will lead them to a cache of money.
As they continue on, Don Wen is seemingly killed in a surprise ambush by spear-wielding tribesmen, and soon the group is captured by a tribe of cannibalistic Amazons led by an effeminate man in a tuxedo. After obliterating the Amazon tribe the group spends the night in a haunted house full of hopping vampires (a traditional Chinese supernatural creature) before reaching their goal.
Once there they find the Generals held hostage gone and the base littered with the dead bodies of Japanese soldiers. Before the group can figure out what has happened they are attacked by sword and axe-brandishing Chinese Nazis riding in 1970s-era muscle cars (it is of note that the highly anachronistic cars are also painted with swastikas and Luftwaffe- style crosses).
Here the plot takes a turn for the melodramatic as the group is wiped out one by one by a machine gun (that clearly does not have an ammunition belt installed), with another killed by a sword in the buttocks. In the end...(approaching character limit)"
Cool, I've downloaded that one. It'll take me some time to get to it, though, as I still have Sonatine, Alien, Aliens, In the Mouth of Madness, Coraline(thanks for the rec Jade), Miller's Crossing, Raising Arizona, Sunshine and Ikiru to watch. I...got a bit carried away with Jdownloader.
