If you don’t do it right, sci-fi will utterly, utterly suck, as this little lot proves. Just don’t expect Zardoz on here because it is better than a perfect film.

Aliens vs. Predator: Requiem (2007)
Wasn’t the world satisfied with one of these cinematic disasters? I guess no. Bring on the idiotic action sequences!

Plan 9 from Outer Space (1959)
Known to many as one of the worst films ever, it’s about as inept as a flick can get, which makes it amusing at least.

The Happening (2008)
The twist is environmental, obvious ham, making it a sad reminder of how far M. Night Shyamalan has fallen.

The Adventures of Pluto Nash (2002)
Supposed to be Eddie Murphy’s return to the big screen, it’s actually a poorly executed example of terrible, terrible ridiculousness. On the moon.

Terminator III: Rise of the Machines (2003)
Kristanna Loken may be hot (100% of the reason people paid to see this disaster), but that doesn’t stop the film from being a giant pile of robot stupidity.

Dungeons and Dragons (2000)
Beyond awful, this fantasy (still kinda sci-fi, right?) catastrophe gave the beloved RPG a bad name and had us all wondering one thing: blue lips? Why?

Star Wars Episode I: The Phantom Menace (1999)
Why George Lucas? Why did you have to ruin everything I’ve ever loved? Also, Jar Jar Binks?

Transformers II: Revenge of the Fallen (2009)
Not only is this film incomprehensibly shot and horribly acted, it’s also ridiculously racist (there are jive talkin’ robots with golden teeth THAT CAN’T READ). Michael Bay, you slime.

Santa Claus Conquers the Martians (1964)
Almost so bad it’s good, it was featured in an awesome episode of Mystery Science Theater 3000, the commentary making it only bearably watchable. Redeeming factor: there’s a character named Dropo.

Battlefield Earth (2000)
L. Ron Hubbard wrote the novel that inspired this magnificently bad piece of cinematic filth. I believe that says it all, folks.
