The brand is dying. Might as well jump ship before it sinks.
I understand not wanting to trash talk someone you don't know, especially when you don't know what exactly they were responsible for. I don't get the praise either. It's easy to just look at the channel and its standing, removed from the individuals behind it.
Look at Cartoon Network over the last five years. Teen Titans Go, Gumball, Steven Universe and We Bare Bears are what would come to mind. Here's the thing. Those shows were either already on the air, or greenlit before she got the job. What we've seen, content wise, seems to have leaned on taking shows already aimed at children (Ben 10, Powerpuff Girls, Total Drama, Thundercats) and making them for even younger kids. DC television animation nosedived. Shows with a runtime beyond 11-minutes are almost nonexistent. The channel became increasingly stingy when it came to acquiring external content, and what little they grabbed would often get sent to die from day-1, begging the question as to why they bothered in the first place. The newest in-house stuff doesn't seem to be getting much attention. Most premieres have viewership similar to years-old Canadian cartoons airing on the Nick Jr. channel. That's why I'm calling this a dying brand.
The biggest positive I can say about CN in the last five years is something I'm not entirely sure she was responsible for. Internationally, Cartoon Network has grown. The foreign channels have more autonomy now and are allowed to make their own local content. That's cool. Good or bad, it's still a shame so little of it gets widely distributed.
