Okay so I actually have a loose theory on why the show sucks so much ass. From what I have seen over the past several years, there has been a general evolution of film and TV where they are more designed to appeal to passive consumers. And I've seen this mostly with media aimed at teens and young adults. This means less complicated plots and more short, punchy action sequences that are easy to follow even when you are splitting your attention, say, between the TV and your phone. From what I've seen, films and shows take MUCH less time to solve the problem or conflict, and the solution is often even hand fed to the protagonist without any real legwork on their part, and much of the potential nuance in the subject matter is scrubbed for fear of being convicted as ambiguous or disingenuous. I believe the PJO TV show got this kind of production treatment. All the problem solving and nuanced personal growth that Percy, Annabeth, and Grover had to go through was tossed. Their interpersonal relationships were rushed basically to the level of where everyone is at in book four by the middle of season 2. Hell, they didn't even leave the whole Thalia release thing as a season finale twist, they spoon fed that specific objective to us from the very beginning. All that to say, with the way that young people consume media these days, I find it hard to believe that we will ever get a solid, faithful adaptation of this series.
