It was good enough. I like the concept of the citadel and it's usually interesting, but I find that citadel episodes often lack significant humor (though in the case of season 5, that's probably a good thing), and the show itself even makes fun of fans who like those episodes the most. Having one or so a season is fine.
This one was probably the weakest of any of the citadel episodes, because it did a ton of recapping of things we already knew, just so the main Rick & Morty could be caught up. But that still puts it in the top half of season 5 episodes.
