Now comes “Sharknado 5: Global Swarming,” and anyone charged with reviewing it has to come to grips with a couple of unavoidable obstacles before even attempting such a thing. For starters—and this is a problem that has plagued anyone who has ever grappled with one of these films over the years—how does one go about analyzing a film that deliberately goes out of its way to be as silly and inconsequential as it possible can? And for those who have found themselves in the seriously bizarre circumstance of having to cover more than one of them over the years, as is the case of yours truly, how does one manage the task without being reduced to rehashing the same observations and snarky comments that have already been used in dealing with those earlier episodes? I cannot honestly say that I know the answers to either of these questions but between posing them and offering a brief history of the entire “Sharknado” phenomenon, for lack of a better word, I have already managed to eat up a decent chunk of my word count without actually getting around to dealing with the film at hand. Believe me, if I could figure out a way of doing that for the entire review, we would all be much better off.

Since the “Sharknado” films are all pretty much the same—increasingly bizarre shark-based storm systems begin wreaking imperfectly rendered catastrophe and the heroic Fin Shepard (Ian Ziering), his increasingly robotic (literally) wife April (Tara Reid) struggle against the odds to save the day and some shreds of their dignity—the screenplays are now more like Mad Libs than anything else. This time around, the people include Olivia Newton-John, Chris Kattan, most of the people from the later hours of the “Today Show,” Brett Michaels, Fabio, Margaret Cho, Fabio, Tony Hawk and no doubt others that I somehow overlooked—to avoid spoilers, I will not cite the circumstances surrounding their appearances except to note that when the Queen of England turns up at one point, she is played by Charo and that turns out to be only the second-most-questionable casting decision on display.

The places include London, Australia, Stonehenge, Egypt, Brazil, Kansas and Japan. (Actually, with the exception of a few London locales, the whole thing was pretty much shot entirely in Bulgaria, a revelation that will surprise no one based on the visual evidence provided here.) The things on display involve hieroglyphics suggesting that sharknados are not a recent phenomenon, a blimp, a mysterious talisman with the power to control sharknados, an especially fierce sharknado that sucks up Fin and April’s young son and keeps him spinning around throughout, an all-female squad of sharknado busters known as the Sharknado Sisters, references to movies as varied as “An American Werewolf in London,” “Raiders of the Lost Ark,” “Mad Max: Fury Road” and “Grease,” and a climax in which Japan is threatened with an attack by what is inevitably described as a “sharkzilla.” The whole thing ends on an uncharacteristically bleak note that only gets bleaker with the announcement that “Sharknado 6” is on the way.
