I actually sat down and watched episodes of the B/W anime recently... needless to say, I was less than impressed.
The Pokemon was, quite frankly, way better back in season one. I know that makes me sound like an old fogey talking about "the good old days" but, at least to me, it seems like the Pokemon anime slowly dropped in quality over the years to the point of disaster.
They keep retreading old ground with their plots (Team Rocket, just give up already) and keep padding things out to ridiculous extremes that it takes forever to actually get from point A to point B. And let's not forget the notion that Ash, canonically, HASN'T AGED A YEAR since he's started.
The games are holding up but I honestly have to wonder why the anime even bothers to continue. I'm just praying that Origins is a much better watch.
