TV THIS WEEK: Game of Thrones comes to an end, Arrowverse and Big Bang Theory finales

Well, the fall season is officially coming to an end — and it's taking about a half dozen fan favorite shows with it this week. The big one is, you guessed it, Game of Thrones.

Fans have waited the better part of a decade to find out who will end up on the Iron Throne, and answers are finally coming this week. Along with the big finale in Westeros, The CW is wrapping up almost all of its Arrowverse shows this week, as well: The Flash, Arrow and Supergirl are ending for the season (the season finale of Legends of Tomorrow is pushed out to next week). Riverdale and Charmed are also hitting their end points. In genre-adjacent news, CBS's hit sitcom The Big Bang Theory is ending its monumental run with a super-sized series finale.

Digging a bit deeper, History's Knightfall is ending its shortened second season, and there's a new episode of Marvel's Agents of S.H.I.E.L.D. on ABC, a new The 100 on The CW, new What We Do in the Shadows on FX, and a whole lot more.
