This week SyFy is doing 'Sharknado Week' in preparation for the Sharknado: the 4th Awakens premiere next Sunday.
It will include such masterpieces as Atomic Shark (it's radioactive and if you don't kill it right, it'll cause a nuclear explosion); Ozark Sharks (sharks versus hillbillies!); Planet of the Sharks (ripping off Guess Which Movie); and Sharkenstein (the ocean's deadliest predators sewed together and reanimated with electricity! And it has Hitler's brain!).
What, you think I made those titles up? Here's some of the trailers.
