Despite being panned critically, the film had some success attracting attention from social media due to its fantastical premise. Websites such as Vulture.com commented on moments from the film. A supposed sequel, "", was released on 1 July 2015. The two films are unrelated in terms of narrative, other than both being films featuring killer sharks.
Plot.
When a great white shark eats the potential catch of a sport fisherman, the man and his daughter violently retaliate by sadistically torturing and killing the shark. The shark's corpse then sinks to the bottom of an underwater cave. It is subsequently resurrected as a ghost shark due to the cave's mysterious paranormal properties. 
Now hungry for revenge, the ghost shark eats his redneck killers, along with the captain of their boat. It eventually sets its sights on the rest of the local community in the seaside town of Smallport, Florida. Due to the great white's new spectral form, it can attack and kill anyone as long as there is even the smallest amount of water nearby. This allows it to emerge out of a swimming pool, a bathtub, a bucket, a metal pipe, and even a drinking cup. It kills many people in several locations.
Though the terror is seemingly out of control, a group of young people trying to find answers end up having their pleas ignored. The local mayor is in the midst of his re-election campaign, and other authorities are unwilling to believe in the ghost. The teenager Ava Conte (Mackenzie Rosman) vows to put an end to the specter, after it devours her father and several friends. She teams up with a local lighthouse keeper, named Finch (Richard Moll). Finch is a drunken figure who claims to know the secrets to the shark's new-found form. After being arrested, harassed, threatened, and otherwise impeded in their struggles, the group then finally manages to lay the creature to rest once and for all.
Reception.
Critical reception for "Ghost Shark" has been predominantly negative. The film holds a rating of 29% on review aggregator website Rotten Tomatoes, based on seven reviews. For example, critic Jim Vorel, writing for "Paste", blasted the film as "a mind-numbing movie", featuring severe problems "[f]rom its performances to its horrendous execution in the editing room". He concluded, "the film violates the most crucial rule of trashy filmmaking— you can be stupid, but don’t be boring." Vorel particularly criticized the fact that the character of Cicily, played by Sloane Coe, is filmed in a sexually suggestive manner in several scenes despite the fact that she is identified as being too young to have a driver’s license (and is presumably under the age of consent).
One of the rare mixed to positive reviews for "Ghost Shark" came from Horrornews.net, with the film given a five out of ten score. The film was labeled as featuring both "[s]pecial effects that would make a film student cringe", but also a "well experienced cast mixed with fresh faced and eager newcomers." The film was compared, both positively and negatively, to an episode of one of the "Scooby-Doo" cartoons. Also, in spite of being panned critically, the film had some success attracting social media attention, with websites such as Vulture.com commenting on moments from the film.
