Is no one going to reply to this guy's post? Alright, I'll bite.
Saying that the anime is not good anymore is completely false. So far, Best Wishes was the only saga that was truly a flop because people actually enjoyed Advanced, DP, and XY. And people have begun to warm up on SM when it turns out it wasn't as bad as many people feared it would be nor was it going to be Best Wishes 2.0. If you still think the SM designs are bad, then you need to watch more anime (I suggest the new Lupin the 3rd anime which had an art style change yet still looks fluent in motion).
First of all, when the show gets bad ratings, it's simply not a good show, period. Back in the Original series, we've gotten a lot of ratings that were in the double digits. Name me one episode as of late that even gets a nine point oh now, much less ranks in the double digits.
Second of all, Advanced was just a downright terrible show that if anything did even WORSE in ratings than Johto did on both sides of the pond (and bear in mind, this was BEFORE YouTube was even a thing), which led to various complaints about the anime franchise such as the girl swapping, Ash and Pikachu getting level resets, no real development due to those aforementioned resets, depicting the Gym Leaders as basically being weaklings, among others. In fact, of the series post-OS that aired, only XY came close to actually MATCHING the OS, and even that was a ratings disaster, with even its movies performing horribly (even Best Wishes' movie sales did far better than XY's).
Third of all, SM only started getting good when they not only started bringing Misty and Brock back, but actually allowed Ash to resume his goal. Don't forget, the entire plot of the overall anime revolved around Ash becoming a Pokemon Master, which was all but stated to require him winning a league. Thanks to forcing him into the school environment, they practically destroyed a key part of the plot for no real reason. Even Best Wishes, a very terrible show in itself, at least had Ash focusing on his goal. And if that's not enough, several press releases for the show back when it was first announced highlighted the fact that Ash's new goal was to "graduate like never before." And that was back last September (ie, September 2016).
Lastly, if you're going to comment about art style/animation changes, I suggest you look at Best Wishes, that had an art style/animation change as well. Or heck, look at Dragon Ball Super, even. They changed their artstyles and animation without being radical about it.
That's just your nostalgia talking because the OS had its fair share of problems as well from logical mistakes, plotholes, and poor writing, and may I remind you that Misty is 10, so calling her sexy would warrant you a target from the FBI.
Sure, maybe the original series did have its own problems in those categories, but it certainly wasn't to the level of those series. And for the record, you should make that FBI comment to Masamitsu Hidaka, considering that, you know he outright admitted he changed girls for eyecandy purposes way back in 2010 in that interview with Pokebeach (and he pretty obviously meant it in a sexual manner). I don't like what Piii said about Misty myself, but I hold Hidaka more responsible since he was the one actually involved in the show.
What about DuckTales, Milo Murphy's Law, and Star Wars Rebels? Those are good shows on DXD too.
From what I saw of the trailers for DuckTales, that show had everyone sounding way too old, especially Hewie, Dewie, and Louie, and the art style really wasn't all that good anyway. And as far as Star Wars Rebels, seriously, the Rebels win every day and makes the Empire look straight up incompetent, which completely conflicts with the opening narrative of Episode IV that made very clear that the Rebels only started having any victories when they stole the Death Star plans (not to mention, it made most of the Empire look as incompetent as Jessie, James and Meowth at their worst, meaning, Vader aside, the Empire wouldn't even qualify as a threatening villain.). Can't comment on Milo Murphy's Law, though, since that's the first I've heard of it.
