Wow, interesting. I had no idea this was a thing.

The animation seems quite strong, and the guy doing Opus seems like a real good voice match. At the same time, Opus seems heavily 'sitcom-cartoonified' here, turning in to a significantly different character, really. Almost a chatterbox, where in the strips he seemed more shy, quirky, and awkwardly clever, if that's a thing.

And yet, that's kinda how it goes when moving a property to TV. So those quibbles aside, it still looks well above average as an animated special.
