Catwoman
Some characters in the Marvel Universe get the royal treatment when it comes to their movie adaptation. Catwoman is not one of those, as this movie has Halle Berry--yes, the famous one-- rubbing cat food all over her face. It received less than 10% on Rotten Tomatoes, and even though it was rumored to be remade, you can't forget this one.
Sharknado
Some movies are so bad, you have to wonder if they were made that way purposefully. This film bravely dared to ask the question "What if a shark was caught in a tornado...would that be bad?" The answer: yes, absolutely. The graphics and special effects are comically poor, the writing is tacky, and the plot is wild. Queue up immediately.
