The good news about “Sharknado 4: The 4th Awakens,” the latest in
the frighteningly durable cable movie franchise that began in 2013 with the
original “Sharknado” and continued with annual follow-ups, is that it s nowhere near the worst of the unnecessary sequels this summer it
certainly doesn’t betray audience goodwill like the shockingly lazy “Independence Day: Resurgence” did. But even the most dedicated of trash movie fans will find their patience tested with this third retelling of an initially mildly amusing joke, along with how Sharknado 4 is just the same combo of demented plotting, dubious special effects and even more dubious guest appearances.
