Regarding the OP's original point: What, so you're saying that Satoshi trespassing even further into Gary Stu-dom than he already has, winning against every trainer that comes his way and blitzing all the championships is going to make the show better?
I'm completely up to date with the latest Japanese episodes. I don't see why people say that the show has become boring. I was reintroduced to the anime at about this time last year - I believe the first episode I saw of Diamond and Pearl was DP060, first aired December 20th - and I was actually surprised about how different it was to the last episodes I remembered. The last I had seen was just over a half of the way through the Johto seasons. Specifically, I was shocked about how much better they were. Even the new dub episodes are vastly improved. The storylines, while often feeling recycled (
DP073 and
EP021,
DP080 and
EP177, for example), often have a fresh new perspective on the plot, and certainly feel like they surpass the old episodes. Take the most recent Japanese episode. DP103 -
Chaotic Mêlée in Mio City! - was a humourous episode, and one which would have been seen as boring filler in the days of Johto or Hoenn. However, 103 was actually one of the highlights of the last thirty or forty episodes, despite the oft-repeated, slightly thin plot.
I don't understand how people can say that the new episodes are boring when compared to older ones. The original series holds fond memories for some, though I think these opinions are rather... clouded by nostalgia. Looking back, the episodes are actually rather poor, in my opinion. They got better as time went by, the artists and the writers improving, but it started to go downhill around halfway through Johto. This was around when I started watching, but I've seen Hoenn episodes since returning to the anime, and their only redeeming features was the improved art. But the new episodes are much improved, and this is obvious in the increasing profile of the Pokémon franchise, at least in the UK.
