As stated, mostly every TV show only shows 1 episode a week. And most season only last for about 3 months, only having 12 to 26 episodes per season. Japan follows the actual seasons, which is why most animes only last a few months until the next year. With Pokemon, we get 1 episode mostly every week, other than with holidays. For example, pokemon is taking a break this week due to a few days long holiday going on.
The start of the Sinnoh Saga on Cartoon Network was showing 8 to 10 episodes a week and then suddenly changed it back to 1 episode a week, which I think 1 a week is better. It doesn't feel like I am drowning in it.
So for the most part, Pokemon goes 4 times faster than most animes and normal shows. So I think it is fine.
