The TV Cave Top Picks

If you're only watching a handful of shows tonight, we'd start with The Walking Dead: Dead City. A season premiere always means fresh twists, bigger stakes, and hopefully a few moments that have fans yelling at their TVs.

House of the Dragon remains appointment television every Sunday, with the battle for the Iron Throne getting messier by the week. Just maybe save dessert until after the episode. Trust us.

Reality TV fans have plenty to choose from as Big Brother enters another critical week with new nominations, while The Real Housewives of Atlanta continues delivering the kind of personal drama Bravo fans live for.

Meanwhile, if you're ready for something completely different, Shark Week returns with an international twist, and Adult Swim expands the Rick and Morty universe with the debut of President Curtis immediately following the Season 9 finale.

No matter what kind of television you're in the mood for tonight, Sunday is packed with premieres, finales, reality competition, prestige drama, and plenty of conversation starters. Grab the snacks, claim the remote, and settle in—because tonight's lineup is giving us plenty to talk about tomorrow.
