I mean it, what's the point of complaining about a show you claim to be your favorite.
The ones who do that probably have little or nothing better to do. Therefore they generate negative energy and use that to cause a chain reaction that may pollute the fanbase.
It is not my favorite and so you may ask why haters like me watch it? Because I have seen the show since the last 8 years. Starting from "I choose you pokemon" in 2003 to the end of d/p. Each and every episode.
So, it is pretty natural that i would want to see the show till its last ep and see what happens in the end.(and there is no point in just seeing the last ep or reading about it on the bulbapedia). It would be pointless to leave the show after watching it for 8 years. If they end the current series with ash as the hero, I'm pretty sure that I will stop watching the anime.(unless they bring in better writers.)
I kinda doubt they'd do that.
