A Ghost Shark Rises

GhostShark.jpgSyfy’s “Ghost Shark” has hopes of scaring up “Sharknado” size ratings.Syfy The “Jaws” theme could have been playing as TV’s background music this summer. You survived the “Sharknado” craziness, the showings of “Jaws” and its sequels, and the Discovery Channel’s annual Shark Week. So, are you all sharked out?

Well, just when you thought it was safe to go back into the cable waters, here comes the Syfy movie “Ghost Shark.” Premiering at 9 p.m. Thursday, it stars Mackenzie Rosman (“7th Heaven”) and follows a group of friends battling the great and mysterious and elusive title creature. Sounds like another unapologetic B-movie comin’ at ya’? Oh, yeah.Writer-director Griff Furst isn’t promising anything else. The ghost shark is a great white returning from the dead after being tortured and killed by fisherman.

Rosman plays Ava. When her father is killed, no one believes that the ghost shark got him — no one, that is, except the crazy lighthouse keeper, Finch (Richard Moll of “Night Court” fame). A 7 p.m. repeat of “Sharknado” will set up the movie’s debut on Syfy.
