Just finished watching the episode. I thought it was okay, but I'm so annoyed that yet another Lucario knows Aura Sphere. I liked the diversity of Korrina's Lucario's moves and now once again they pull out the apparently obligatory Aura Sphere.
I one that aired yesterday? I really liked it. I loved the teamwork between the group and how they all worked together to catch the poacher. Though I personally would have rathered that Serena be the main focus and bond with the Spewpa instead of Ash and then end up catching it, I was fine with it overall.
