Lots of massive changes happened from Sinnoh to BW

Animation changes, Brock going home, Ash regressing in League development, Ash capturing more then 5 Pokemon(hasn't done this since Kanto). Ash becoming the 'sole' main character since Contests have been abolished. Do you think this has made BW better or worse? Do you think the writers will continue to implement these and future changes or should they to back to their roots from Original to Diamond and Pearl?

Discuss.

Personally I think they should of kept contests and the maturity that Ash had been developing for the 14 years prior to BW. I also miss the development of his team. It's been poorly handled this generation.
