Risa

I only have vague memories of most of it from watching it as a kid, but recently my spouse and I decided to give it a watch one night and made it through the first 7-ish episodes. About half of the stories were "meh" but the other half were actually pretty good by TOS standards.

Mind you that's just the stories. The animation itself is definitely a limiting factor, and a lot of what happens is either very sparsely animated or they literally have characters explaining what's happening rather than fully animating the events. A weird upside of that is that most episodes are practically radio plays, and you can just listen to the audio and understand what's going on.
