Their schedule is oversaturated in Teen Titans Go. While some episodes are mediocre at best, a good deal are horrible. Whatever "moral" they throw around comes off as ham-fisted despite being a parody moral, meaning it sends the wrong message. Other times, it feels like they're insulting their critics and ignoring their own flaws. Tiny Titans did the concept much better.
Powerpuff Girls 2016 - This show was suppose to be about cute girls in a world of tough villains. The Slice-of-Life take on it ended up damaging the show. And when did they suddenly get Green Lantern powers? I did really enjoy their crossover with PPG though.
Steven Universe really is still good. I like the mythos but the style of animation isn't my taste.
Their main problem is that they constantly shove their shows in favor of what's popular, making it have the Disney Channel Effect. The more minimarathons you show, the more annoying the show gets.
"Everyone creates the thing they dread. Men of peace create engines of war. Invaders create Avengers. People create... smaller people? Er... children! I lost the word there. Children. Designed to supplant them. To help them end."
"Resistance. Rebellion. You will burn these ideas away."
But this is the traditional royal Canterlot voice! It is tradition to speak, using the Royal "we", and to use THIS MUCH VOLUME WHEN ADDRESSING OUR SUBJECTS!!
