BBC's Sherlock.
Most episodes of that show I can rewatch endlessly. Tons of Doyle's work got at least passing references, but man, the way Study in Pink modernized the storyline was just masterful. Would love to give them more goes at really modernizing classic Holmes cases.
I think they were going to continue Stargate for the fans, but Amazon cancelled it because it wasn't for the modern audience. You are making it for the existing fanbase, we want a new fanbase. A well-trodden road with Disney Star Wars, Kurtzman Star Trek.
Young Justice may not count as the future is uncertain but i'd love another season as there are several loose ends that i'd like to see be used
examples wich also are spoilers: Red hood has appeared but only played a minor non speaking role, kid flash is in speed force purgatory and i'd love for him to get out off there, a server in one off the last scenes (if i remember correctly as i haven't watched since last season aired) was wearing a ring which is one off a hero so would be nice to see that hero actually appear
