I sometimes get bored and watch an episode. I don't really watch the show anymore ever, but I did catch the first four or five episodes of B/W by pure chance. The issue I had was why did Ash get dumber? He like forgets everything including how to catch a Pokemon, yet he just made the T4 (I think) of the previous Region. To me that makes no freakin' sense. I mean why did he lose all the knowledge he learned from the past 10 years of the show. He has never had an issue knowing how to catch Pokemon and what types to battle save for the first season (which was understandable), but to go back just makes the show completely unwatchable, if it wasn't already that way.
I do understand about Brock not being on the show. They wanted to promote more of B/W in the show. However, not sure that I agree with the choice after seeing those first 5 episodes.
Just my thoughts on it.
