This show has done 2 things at once,
1. Made the art form of Anime look stupid and childish
2. Tainted a much-loved series
I watched most of the first episode and found it a confusing, aimless mess. What were the producers of the original thinking? It was like letting a pack of starving racoons lose to do brain surgery.
I have to say I am a huge R&M fan, and I found this very insulting to myself as one of their fans. If someone had neither seen Anime nor Rick and Morty, this show would kill any desire to view anything else from either of these two. I would strongly warn anyone from watching this series. Other reviewers here have echoed some deeper comments, and for the most part, I totally agree with them. Even Velma might just be better that this.
