Oh hell yes! Despite a points deduction for hammerhead bludgeoning of Xfinity and NBC and Universal logos, characters and products, the Sharknado formula is finely honed here and well worth watching. A Washington, D.C., opening sequence, jam-packed with cameos, would be movie enough for some reviewers (OK, maybe this one too). But, no, the entire “Feast Coast” is under siege. And how do those sharks survive in space?
