Even the existing characters had unique designs and some cities really look great, but it lacked interaction, an involving storytelling. Even though many people in /vp/ hated. SM and Gen 5 did that right (Platinum could be mentioned too) and probably from now on every game with a story that gets worse than that will probably be shitted in those terms.
Also, XY had a big Pokedex and made it also a mess. Lumious had a big hype over it and ended up being big and tedious. It's clear they didn't even thought too much about the gameplay itself.
