The movie is about Finn, who faces a strange fate five years after the 'Sharknado 3'. Finn has years of peace raising his son born in April, while there is a mysterious pathway caused by sharks and hurricanes in strange and unexpected ways and places.
Long gone is Parts 1 and 2's wry delivery of witty-ish dialogue, replaced instead with expected gags - save for an actually engaging scene where Fin and April sorted through the subterfuge and lies they each had been fed during her five-year absence.
Whatever absurd delights this series once could boast have long since been stripped of their tiny joys and ground into dust by the weight of encroaching, ceaseless, incredibly cynical commercialism.
The 4th Awakens gives off the impression that the Sharknado franchise has locked into groove where it can give its fans more to talk about on social media while staying true to its B-movie creature feature/disaster film roots.
What was once a guilty pleasure has now said farewell to the pleasure part of that equation, and what's left is just so much light and noise that sweeps away the things to appreciate.
