I actually think this was a very nice episode: the COTD's backstory was actually pretty interesting, Ash and Max had a cool dynamic going with each other helping out that Shroomish in the streets, while finally Brock was frightened to death of going to the Mansion but May dragged him along-- I thought that was hilarious, actually.
Team Rocket was actually alright as well, so that was nice.
