If you like the original Rick and Morty and you want more of that, then you will absolutely hate this anime. This truly is an anime. It is not a comedy, it's not an American adult animated show at all, in any way. It was made by an actual anime production studio in Japan and it was made in exactly the same way that any other anime is produced. This means that there is even a considerable difference between translations for the English subtitles and English voice dubbing. This was a detail that most anime fans probably wouldn't even expect. This is not even like Avatar, which is often considered American anime.
If you watch the show expecting a dry science fiction anime like Planetes, then you will not be disappointed too much. As far as dry science fiction anime goes, the Rick and Morty anime is not bad. It is highly stylized and avoid anime art tropes. It doesn't waste time with extremely long plot dumps. Only one episode is out though, so I can't review the story at all. I can say the first episode does not have a good hook at all, which is why most people are calling it boring. Like many anime, the first episode is boring. The second or third episode could be incredible though and the list of classic anime with boring first episodes is very long.
If you don't like anime, don't watch this. If you are a Rick and Morty super fan, don't watch this. If you really liked Planetes twenty years ago, then you will probably like this to some degree.
