This whole thread is making me wonder one thing: what is this 'Kanto feel' anyway?
Really, we talk about reclaiming it and so on and so forth but there's no real confirmation over what it even is. I've seen someone say slapstick but there are many shows that have slapstick that don't feel like Kanto. I know nostalgia is an obvious answer but there are people who talk negitively of it and there are various posts from people who use the phase that show a complete lack of nostalgia. It can't be the original trio since they were kept in Johto and that has a very different feel (even if you remove all the fillers.)
Why does the show have to feel like Kanto anyway? DP was the best season and that was almost as far from Kanto you can get without it stopping being pokemon. Both Johto and Best Wishes appear to be trying to be like Kanto and are the worst seasons yet... though Johto less so and in all honesty there's at least some honesty in Johto's rubbish moments, like it knows it could be better whereas Best Wishes is more...
The fillers in Best Wishes tend to pretend to not be fillers. They put in captures for pokemon you never see again. The Gym episodes feel more filler like thanks to the downhill path of the battles.
