Earlier this year the Syfy movie Sharknado set the internet abuzz with a whirling mix of meteorological activity and razor-sharp teeth. Now its creators are back with another campy tale that's sure to please fans of this very particular brand of TV movie. Mega Shark vs. Mecha Shark is actually the third entry in the Mega Shark franchise, following such "classics" as Mega Shark vs. Giant Octopus and Mega Shark vs. Crocosaurus. It basically boils down to a really big shark fighting a really big mechanical shark, which should be more than enough to convince you to watch the trailer right now.
