We didn't think it was possible, but Sharknado 2 has really raised the whole "sharks in tornados" aspect for the follow-up movie. This teaser trailer for the sequel really sets the bar high when it comes to hitting people with sharks falling out of the sky.
Also, Sharknado is now doing good in the world of sharks (not the kind in tornados). Sharknado 2 will sponsor shark conservation research, which is a nice thing to do.
