If you've ever wondered what part of Rick and Morty is Roiland's and which is Harmond's, just watch this show. While it showcases Roiland's manic improv, it lacks the character introspection and pathos that made Rick and Morty a success.
Without Harmond's guidance, there's just not much to root for about the alien family. Typically some random shit happens, then things go from bad to worse because aliens. None of them are particularly likable. Some gags are fine but on the whole it all feels pretty skippable.
If you are looking for the typical retelling of this well known fable. Don't bother. Otherwise come for a somewhat new view on the legend of Count Dracula.
