I really enjoyed watching this series, especially the last two episodes of season two! All the characters have a very striking background which I absolutely respect and the humor is fantastic. Lastly, the song choices are spot-on, I literally can't stop listening to "smells like cherry" by Alex Vas, it's too good. I'm really looking forward to seeing more progress with the animations and plot of the show :)
P.S. if you go on wiki fandom each of the metal family members has a playlist of songs and some of them are pretty good :D
