It has taken me a long time to get into Pokemon Horizons. I think it took like 10 episodes, so almost the entire first part before I began to really enjoy it. I have to say, I like them a lot. It also shows just how incredibly strong Ash in compared to your average pokemon trainer. Yeah Ash himself has had ups and downs, but after seeing a series with completely new trainers, away from gym leader traveling companions and what not.... you can see why Ash in the World Champion.
Right now I am liking Roy more, but I think it is because he is more so the new Ash when it comes to the way he acts atm, but I also like Liko. Dot just told Liko the truth about somethings, so we will see how Dot's character changes from there.
