10. 'Highlander II: The Quickening'
"Highlander II: The Quickening is the most hilariously incomprehensible movie I've seen in many a long day — a movie almost awesome in its badness," Roger Ebert wrote in his original review of the film. "Wherever science fiction fans gather, in decades and generations to come, this film will be remembered in hushed tones as one of the immortal low points of the genre." As always, the man was 100 percent right. Don't even attempt to say the words "Highlander 2" in a group of nerds. They'll cover their ears and start screaming until you stop. Beyond all the other problems, the plot doesn't even make the tiniest bit of sense. Future editions tried to remedy this, but it was too little too late.
