Last weekend I watched a TV event that was probably inevitable: a SyFy movie called “Jersey Shore Shark Attack.”

It was immensely satisfying: a spoof of both “Jersey Shore” and “Jaws,” cheerfully low-budget, with computer-generated sharks and obviously plastic dorsal fins and the occasional severed limb, squirting blood. The “Jersey Shore” cast was loosely re-created (“Nooki,” “The Complication”), and a former member of NSync — not Justin Timberlake — was killed by a leaping shark before he could sing a note.
