Medium, the game. It was never bad, but it never set out to be incredible either. It's a very easy and short game, although Kalos is a beautiful region. The story is really silly, especially following generation 5, but it's completely fine as it's a Pokemon game. The postgame is a barren wasteland, though. All in all, it succeeds at what it sets out to accomplish ; it's meant to be the transition between 2D and 3D for future games.
Oh and MEGA EVOLUTION IS PEAK YEAHHHH
