This Week's TV: Adventure Time Reveals Finn And Jake's Parents' Past

This week, Discovery hosts its celebration of all things shark, but which specials are worth watching? We've got you covered. Plus, we're nearing the end of True Blood; mini golf gets serious on Gravity Falls, and we get to see the mystery-solving past of Finn and Jake's parents on Adventure Time.

Shark Week is upon us once again, and while it's a great opportunity to delve into shark science, the programming can be a mixed bag. While some of the Discovery Channel's shark-themed specials talk about the science of sharks, some are designed to inspire little more than terror of these magnificent animals. We've listed the programs recommended by the oceanic public relations firm Upwell below, but that doesn't mean that the specials are necessarily perfect—and you can also read about all of the programs at the Discovery Channel's website. Discovery also has links to some incredible Shark Cams. Steer clear of that Megalodon documentary airing on Friday. It's just plain fake.

When in doubt, it's a good idea to follow actual shark scientists, like David Shiffman, on Twitter to see what they're saying about the Shark Week shows. For example, last night's airing of Shark of Darkness was filled with misinformation. Enjoy Shark Week, but don't take everything you see at face value.

This week, the exploration of science fiction tropes returns to celebrate all things time travel:

What price does the time traveller — and the people they are closest to — pay? This is a journey from H. G. Wells' The Time Machine through ideas like The Grandfather Paradox and The Butterfly Effect to the professional time traveller that is the ever popular Doctor Who. Steven Moffat, David Tennant, Karen Gillan, and Neil Gaiman offer a unique perspective on the Doctor. Edward James Olmos reveals the hidden meaning of the language he created for the vision of the future that is Blade Runner. Bob Gale and Christopher Lloyd take us behind the scenes of Back to the Future, while Ed Solomon describes the joy of solving a time travel conundrum for Bill & Ted's Excellent Adventure. But what would be the physical and emotional cost to the time traveller? Audrey Niffenegger explains what inspired her novel The Time Traveller's Wife. And what if someone from the future tried to travel back in time to warn us? Would we believe them? From the apocalyptic tones of 12 Monkeys to the drama of Quantum Leap and the comedy of Groundhog Day, time travel is a subject that has been irresistible to the creators of every type of science fiction.
