Shark Week, "Return of the Great White Serial Killer" and "Alien Sharks: Close Encounter" (Monday, July 6, 9/8c and 10/9c, Discovery)

Discovery is calling this the "Summer of the Shark," and they may be onto something. This summer marks the 40th anniversary of Jaws, which pretty much invented the summer movie blockbuster. Discovery has had such great success with its "Shark Week" franchise, now in its 28th year, that it has moved its annual orgy of shark-tastic documentary features to early July, and plans a special "Shark Week" weekend in August, with a record 19 hours total of new prime-time programming. (In between these shark wallows, Syfy will deliver the supremely guilty pleasure of Sharknado 3: Oh Hell No! on July 22. Don't say you weren't warned.)

Tonight's main attractions include Return of the Great White Serial Killer, in which two shark experts head to Surf Beach, Calif., to explore the pattern involving fatal shark attacks that occurred on the same beach in the same month two years apart in 2010 and 2012. Would there be a repeat occurrence in 2014? And Alien Sharks: Close Encounters is the third helping of the fan-favorite Alien Sharks series, in which high-tech cameras go into deep, dark ocean depths to reveal some of the planet's weirdest watery predators—this year, including a 20-foot mega-mouth shark off the coast of Taiwan. Sounds fascinating. From a distance.
