The title of this 2014 sequel suggests how tongue-in-cheek the filmmakers are approaching this, and viewers should approach with that in mind. Ian Ziering and Tara Reid return for this second go-round, which is less of a draw than cameos by Kelly Ripa, Matt Lauer, Robert Klein and Viveca A. Fox. The true draw, of course, is the idea of the gloriously cheesy special effects, approximating giant funnel storms that deposit killer sharks all over New York. Personally, I’m waiting for a variation on the theme, one that would marry meteorology and zoology in even more bizarre ways. Why make more than one Sharknado? Why not move on to other grafted animal-filled storms? Submitted, for your approval: airborne bison in Herdicane. Piggish Northern Lights in Aurora Boar-ealis.  And, last and probably least, the potentially R-rated weather thriller, Kittytwister.
