Tuca and Bertie is absolutely delightful, and everyone should watch it if only to encourage more female-written and female-focused shows like it. Apparently it's only the first or maybe second woman-helmed adult-focused cartoon that's actually gotten a full and well-publicized season, which is insane, but I can't think of a better standard-bearer if it manages to improve the genre.
Given that, though, it feels a little weird that the thing I'd most congratulate it for outside of that is how well they did the male lead. But I actually think that factors in a little more than first seems, because Speckle's role is very much what's typically a female role in other shows: The balanced, level-headed person that acts to tell the main characters that they're Wrong And Bad (basically, the wife character in... literally anything I can think of that has 'the wife character'). But they remember to make sure he's always got a pretty good point, and that he's a pretty fun character to have in a scene no matter what he's doing--mostly just by having the most fun they can with making him a really boring guy.
