Most people would just say this anime is a clone of Naruto, simply because Asta and Naruto are similar minded MCs. But all shonen anime have similarities, and for anyone who has put the effort into watching most of the episodes, then it's evident how unique Black Clover really is.
Story 10 - The story goes about at a fast pace, it doesn't take long for Asta to become strong, which I've found can be bad at times (Fairytail) but the pace is perfect, there's hardly any fillers (for a weekly continuous anime this is amazing) with the story being very well thought out whilst easy to follow all in one.
Art 8 - The weakest part of Black Clover isn't even bad, it is great. There is room for improvement, but the world and the magic is beautiful, all the characters designs are distinguishable. The fight scenes are great also.
Sound 10 - Hands down the best intros in anime history, some of the best voice acting around today too.
Character 10 - I never thought I'd watch an anime with better side characters than Naruto, but I may very well be in the process of witnessing this, as it is still an on-going series, I will reserve judgement when it is finished. Many characters are well thought out and the female character aren't just eye candy in this show, they are some of the best written characters. It's fantastic to witness.
Enjoyment 10 - Every week when it's anime time, the first episode I watch is Black Clover, it's brilliant in so many ways; reliable, action, romance, comedy etc.
Overall 10 - Recently discussed with myself if this should be a 9 or 10, but decided that it has to be a 10, it is so well rounded and has a large fan base growing, it gets attached a lot by fans of other series, but that's always a sign of a great anime.
