Black Clover is one of those Series much like Naruto or Akame ga Kill where NEW anime viewers and younger weeaboos who haven't been exposed to all the generic anime clichee's and stereotypes in droves will make the incorrect assumption that the show is somehow unique, and/or will let their obsession to anime delude them into thinking it's good because they convince themself that all anime is good, basically if you have NO taste or opinions of your own then it seems good
but if you have actual taste and know what is and isn't a good anime you will hate it, so if Toonami wanted to Bring in new teenage anime viewers then they'll probably succeed with Black Clover, but all of us older anime fans are gonna be in agony
