I think Im the only person, ever, who liked Battlefield Earth
Bad movies though? hmm, Zoolander, couldnt watch more than the first hour because of how boring it is, Ive since heard it gets funnier after that so I might give it another go.
Grease 1&2, If it wasnt for teenaged girls that film would have never been popular
Big Fish, truely terrible film, I think a mugging would have been less painful and more enjoyable.
Love actually I also found pretty awful.
And thats just the tip of the iceberg really, there are a lot more but I cant think of any right now (Probably mentally blocked them becuase they are so awful)
