It worked at the time but Ash was too shallow and the trend of protagonists like Kirito from Sword Art Online was coming to an end, characters with a lot of expressions and emotions were becoming successful, so they decided to do the same with Ash in Alola. It's not strange that Alola Ash is hated by kids, the same ones who self-inserted themselves in XY.
