I love Disney (and especially Disney World, even if they're changing things I don't want them to. I try to go there as often as possible, even if it means once every 6 years), even if they do annoy me sometimes, but:
They have, like, a bajillion dollars away in storage. So, would it kill them to finish what they start? Why would they release 85% of Ducktales, but then stop and not release the last season? Was it really doing that poorly? Even if it was, the loss was probably like a penny in the ocean - suck it up and finish the job. I mean, really now. Argh.
