This is not a list of the worst movies and the best movies that came out this year. Those you can find anywhere, and everyone's opinions differ on that. This is a list of the worst-best movies of 2011. What do we mean by worst-best movies exactly?
These movies are so ridiculous, action packed, gross, or unrealistic so as to be horrible by many people's standards, and therefore, kind of awesome. These movies were controversial, movies that everyone said they hated, and that tickled the gag reflex. Movies that were, perhaps, so stupid, pointless, or unrealistic that they will never be forgotten.
The first movie on the list:
Fast Five. Anyone who loves
The Fast and the Furious 
series should love
Fast Five, as it carries on the traditions of the series quite well. Although in many people's opinions it wasn't even a little bit good, that doesn't change the fact that thousands loved it. Not everyone likes the genre or the irrational, non-existent plotline, giant explosions, and mediocre acting, but those that do are in for an unforgettable experience.
And if you want unforgettable, in the worst way possible, Hobo with a Shotgun is your movie to watch. Hobo with a Shotgun has it all: lots and lots of violence, guns, and blood. At one point, someone's brains splatter (very visibly) against the windshield, and at another even worse point, someone's head is pulled off with a chain attached to a truck. It's disgusting, to say the least, and therefore unforgettable. Not one for sensitive viewers.
Then there is the last and ultimate guy movie ever made: Cowboys vs. Aliens. Does it get more awesome than that? According to most people, no, and although the movie in itself sucked, there was action, hot girls, and best of all, cowboys fighting aliens.
Yes, all of these movies were pretty horrible. Yes, the majority of the world didn't like them. And that's what makes them so popular with the select few.
