Chainsaws, sharks and tornadoes — this is the dream that was brought to life nearly six years ago when Syfy greenlighted the production and release of “Sharknado.” Full of bloodthirsty, airborne fish, the low-budget feature film has since developed into a hexalogy of movies that are now a staple of pop culture.

It is sad to say, however, that the franchise has far exceeded its expiration date. What started as an inside joke is now a running gag that has long lost its novelty and any sense of comedic value.

Syfy’s aptly named final installment of the Sharknado franchise, “The Last Sharknado: It’s About Time,” brought the series to a much-needed end on Sunday.

Picking up from where the fifth installment left off, “Sharknado 6” begins with All-American hero Fin Shepard (Ian Ziering) stranded on a desolate planet after having unleashed a sharknado apocalypse. He is the lone human survivor and wanders the earth with his wife’s severed, robotic head until his aged son Gil — who was lost in a sharknado the previous film — comes to his rescue in a time-traveling car. After being reunited with his crew in the land of dinosaurs, Fin must traverse across time to vanquish sharknados and reset the timeline.

Though it is meant to be outlandish and “spoofy,” Sharknado puts far too much effort in creating zany plot points which are frustrating to watch. Yes, it is a film about flying sharks and yes, it is meant to be horrible, but Syfy somehow botches making a terrible movie.

The original Sharknado film was great as it was able to include as much oddity as possible while also maintaining a relatively coherent storyline. It was a simpler time in life where a sharknado was just that — a sharknado.

The most recent movie, like the preceding few, failed to accomplish this, instead choosing to prioritize eccentricity over all else. Granted, sometimes the extreme levels of peculiarity are awarded, such as when Neil deGrasse Tyson appears as the sorcerer Merlin and says, “Who needs science when you have dragons?” Despite the occasional laugh, the majority of the film — like the majority of the franchise —  is simply strange and, at times, even cringe-worthy.

After more than half a decade of sharknados, the franchise has lost its originality and no amount of oddball behavior can bring that back. What could have been the best awful film of this generation was weighed down by a continuous stream of sequels that fulfilled no purpose besides losing the interests of a once engrossed audience.

An inevitable fall from grace, “The Last Sharknado: It’s About Time” marks the lackluster conclusion of a once great idea.
