It’s here: The Last Sharknado: It’s About Time. Stuart Heritage offers a valedictory, if that’s the word: “[The first Sharknado] had an irresistibly silly premise (a tornado made of sharks threatens America), a knowing line of stunt-casting (Ian Ziering and Tara Reid) and a big fat wink instead of any emotional stakes … As tends to be the case with successes like these, sequels were greenlit that only helped to diminish the punchdrunk silliness of the first film. Slowly, the films began to eat themselves.”
