I think that the issue is that there are a group of intriguing episodes coming up and there was really nothing really great that stood out about this two parter. Nothing really happened and Team Rocket did not really have a larger plan than just steal Pokémon X. I think that if there was more to it, people would have had a different reaction. Many people don't think that a steal Pokémon X plot really deserves a two parter. I've only seen the pictures so I'll have to watch the episode before I can make a more informed decision, but the pictures made it only look okay, and a far cry from the usual quality of BW episodes, especially compared to what we know of the next three upcoming episodes.
Team Rocket will pay for their crimes.
