Episode itself was pretty subpar. We had Ash heading alone toward Hoenn leaving all pokemon behind and taking Pikachu with him. Only intriguing thing was TR and battle between Arbok and Weezing. I certainly didnt welcomed another overused scenario of good guys being paired up with TR having to overcome their differences and work together. Perhaps it would be more enjoyable if humans got paired(reason why i liked "Forrest Grumps") but seeing Pikachu and Meowth going on solo mini-adventure wasnt something to write home bout,although Hinter was fun and i guess TR magnet provoded half-decent reason behind Pikachu usual regress in strength at start of new region.
There is a reason why out of all existing groups in pokemon, biggest demand exists for original trio reunion. Out of all replaced girls biggest demand is for original girl return too,which explains many things.
