I love this show because of the premise and the idea that we could all improve our lives by just making smarter choices. It's also fun with a likable protagonist.
Even though I would have loved to see a season two, I can understand why this show was cancelled.
-- The protagonist, Brian is laid back. I get it. He's showing that he's a regular guy the audience can identify with. But ultimately, it undercuts tension for him to be a party dude in a thriller. A show that played this well was Psych.
-- The show is laden with soap opera dramas that linger too much on emotion and don't ultimately change the big story. Whenever the father shows up, for example.
-- Although the show has a high-level story arc, it is fragmented. Without a strong sense of purpose, and momentum, the high-level story can't be gripping. I got the sense that there wasn't a well-mapped-out big idea driving the backstory and mystery, but rather guesswork by the writers.
-- Beyond the high-level story, the procedural nature of the show underserves its premise (an intelligence pill), and the smart cop thing has been done before. It's Sherlock Holmes all over again. It's so repetitive that the show has to keep coming up with unusual crimes and unusual crime-solving methods. But a TV show shouldn't be about the mechanics; it should be about the people. The premise naturally leads to more of a thriller / horror / drama like Breaking Bad or The Man in the High Castle.
-- Plot holes take us out of the show. I get it, a cop show isn't supposed to be realistic. But there are some sloppy twists and turns, choices that don't make sense for the characters or their organizations.
-- The show seemed caught between celebrating the intelligence drug and showcasing the horrors of addiction. You can't do both. It learned more towards the celebrating. I read online that the superpowers coming through a pill-based drug was a major factor in the show not being renewed. It's too close to the implication, "taking cocaine is okay if it makes you productive".
-- Finally, and most fatally, one of the show's heroes is under the thumb of (omitted), and gives in too much, seeming not to be bothered when crimes are committed. A protagonist with moral failures becomes less likable, less easy to root for. There should have been a giant struggle there instead of camaraderie, like in Daredevil and Luke Cage fighting the organized crime trying to blackmail them.
A lot of TV shows have a bumpy first season, for example Star Trek the Next Generation or Veep. I would love to have seen if they could have turned this into a miracle show. And I still love the premise. But I think structurally, there was too much wrong with this. So I can see why they cancelled it.
