The voice actors are flat out terrible now, not the voice, but how they emote certain lines and how they talk. They really only have one emotion and you never feel like it's genuine. I notice this change when they changed voice actors in the middle of Hoenn, but it really didn't get bad. Until Unova where they just became dolls that spoke in one voice.
Plus the theme songs, are sung by someone who is tone death, because they picked some awful singers around the middle of D/P saga.
