1. Darkwing Duck not only aged the best between it, Ducktales, and Goof Troop (seriously, I'm sure GT only gets talked about on the 'net from all the porn with Pete's wife) but was the one that most deserved a reboot. Speaking of reboots, I've been underwhelmed by the tone of Ducktales 2017 (in a nutshell, the characters come off as not really taking what they do seriously).
2. Star vs. The Forces of Evil should have either never tried to be anything other than wacky shenanigans or the showrunners should have planned out a show bible with the world, politics, characters etc. ahead of time (if only to make the dindunuffin characterization they pulled with monsters more credible rather than at odds with all the mustache twirling supervillainy we see). Even then, the show never got any better than Toffee's (who with Ludo made a nice villain team, much better than later villians) big scene and sendoff. I can go more into problems with the plot and/or setting but this isn't the thread for that I'm sure.
3. The production version of Frozen was more interesting than what we got.
4. The Loud House is just a meme cartoon that became a meme from the girls.
