That's tough. I picked Aladdin but I liked them all quite a bit.
Why are none of these on Netflix?
Good question considering they have a deal with disney in place. I wouldn't be surprised if we see most to all of them eventually.
Having done a tiny bit of work with film contracts, I'd imagine that it's probably stupid rights issues preventing these from being streamed. Most of these Disney shows were created to be syndicated, so the producer's contracts most likely afforded them a profit share for as long as a show was aired. Streaming through a service like Netflix could give some of those folks ground to sue for lost pay, as it's slightly similar to syndicating a tv show, and that's a headache that most likely outweighs the probably minuscule profit that Disney could stand to make.
Also, Disney plans all of their efforts around supporting IPs, and as most of these shows probably won't be "rebooted" any time soon, they're even less appealing to the company.
Darkwing Duck without a doubt. I started watching it before I got into Ducktales. I liked Gargoyles as well but felt the show lacked a proper resolution following Gargoyles The Goliath Chronicles.
Shnookums and Meat had one fun side show called "Pith Possum, Super Dynamic Possum of Tomorrow". It was a superhero show parodying the 60's Batman show, but it also reminded me of Ralph Bakshi's Mighty Mouse, the New Adventures from the 80's.
I used to watch all the shows. By the way, I think in addition to Here's Bonkers being left off the list, so is Disney's 101 Dalmatians The Series. Not a great show, but they made 65 episodes so it wasn't a minor offering.
