TV THIS WEEK: Game of Thrones' finale, True Blood's farewell begins and more!

This week we end another season of Game of Thrones, and prepare for the final season of True Blood.

It's been a great year for HBO's epic fantasy series. Game of Thrones started the season as something really popular, and it's ending it as the most-watched series in the history of its network. This week Thrones closes out its fourth year, and we get set for the seventh and final season of True Blood with a farewell retrospective. Plus, The 100 and In The Flesh end their seasons, Believe ends its series, and a special guest director leads Adventure Time

Highlights of the Week

The 100 (The CW) Wednesday, 9 p.m. - "We Are Grounders, Part II"

Season finale! - The 100 arrived earlier this year to fill yet another slot on The CW's schedule with a genre program, joining other freshman genre series like The Tomorrow People and The Originals. Based on a young-adult novel and set in a post-apocalyptic future, it seemed poised to capitalize on an audience captivated by things like The Hunger Games and Divergent. It hasn't maintained the same audience strength as Arrow or The Vampire Diaries, and it hasn't yet established the same fierce loyalty that shows like Supernatural have earned, but The 100 has done well enough to snag a second season on a network that's increasingly packing its schedule with genre fare. Now, as it prepares for a second season alongside network mates like ArrowThe FlashThe Vampire Diaries and Supernatural, we all will wait and see if The 100 can grow to be a bright spot on its network, or a show overshadowed by its flashier companions. As season one concludes, Octavia faces a tough choice, while Clarke tries to persuade Bellamy. Check out a preview below. 

Adventure Time (TOON) Thursday, 7 p.m. - "Food Chain"

Some of you might find it odd that we've added Adventure Time to our weekly TV roundup, while others probably find it even odder that the show wasn't on our list already. The acclaimed animated fantasy series has grown from plain old hit to full-blown pop-culture phenomenon over the last few years, and when it returned for its sixth season in April it was welcomed back by more than 3 million viewers. Adventure Time's popularity shows no signs of waning, and after more than four years on the air it remains one of the most creatively ambitious shows on television. So it's on our list now. As for what makes it a highlight this week, well, that would be the presence of Japanese animator, director and writer Masaaki Yuasa (KaibaMind Game), who wrote and directed this week's episode, in which Finn and Jake learn about the food chain in the Candy Kingdom Museum of Natural History. Yuasa's surreal style is a perfect match for the already crazy series, as you can see in the clip below.

Believe (NBC) Sunday, 9 p.m. - "Second Chance"

Series finale! - Believe had an early pedigree that made it look like it could go the distance. Co-created by Oscar winner Alfonso Cuaron and produced by genre juggernaut J.J. Abrams, it was immediately buzzworthy, and though the pilot episode attracted a solid 10 million-viewer audience, the interest didn't last. Most of the episodes since have averaged less than half the premiere's audience, and the show's ratings scores in the key 18-49 demographic dropped even more sharply. So all of Believe's potential fizzled into a one-season series, and the viewers who are still devoted to it will have to settle for Sunday's episode as the ending of the saga. On the finale, Dani plots Bo's destruction. Check out a preview below.

Game of Thrones (HBO) Sunday, 9 p.m. - "The Children"

Season finale! - Game of Thrones has set several personal bests for viewers this season, but this past week it cleared an even more impressive hurdle when its gross total viewership across all platforms hit 18.4 million viewers (and that's not even counting all the people who pirate the show every week), topping the best The Sopranos ever did to make it the most-watched series in the history of HBO, a network that's repeatedly brought us TV giants like The SopranosSix Feet UnderThe Wire, and Sex and the City. There seems to be no stopping this show, and the season finale seems poised to deliver plenty of new surprises to keep viewers hooked well into season five and six, both of which have already been ordered by HBO. For the moment, the question is not whether Game of Thrones will stay big. The question is: How big will it get? In Sunday's episode, Daenerys faces the harsh reality of her struggle for power, Tyrion faces his fate, Bran discovers more about his destiny, and a new arrival will change the struggle at The Wall. Check out a preview below.

True Blood Farewell Show (HBO) Sunday, 8:30 p.m.

Retrospective time! - True Blood doesn't return for its seventh and final season until June 22, but before the final 10 episodes begin airing, you can start your goodbye to Sookie, Bill, Eric, Tara and the gang with the half-hour retrospective that features some of the key moments of the past six seasons. It might be time for it to go, but HBO will still miss True Blood. Until Game of Thrones passed it last year, it was the network's most popular (currently airing) series, and its rabid fanbase might be hard to replicate. For now, though, we get to see how well the final season performs, and that begins with this little sendoff special.
