So glad I didn't drop this series completely. I dropped Black Clover once over the new Japanese voice actor at the time (same voice actor as Shinra from Fire Force). Picked it back up after thinking I didn't give it a fair chance then almost dropped it again from boredom. It takes a bit to pick up but once it does it's so amazing that not only did I binge watch it but I bought every single manga volume available at that time in a single day and have been collecting them hereafter, now it being my favorite currently running anime. Here's some common complaints:
•Generic: I disagree it's generic, at first this may seem to be the case however the story involving demons, elves, magic, curses and characters with the storylines is anything but generic. The main character is powerful of himself and doesn't do these speeches or hero of Justice mantra's and is very relatable in how he acts from slapping someone to snap out of something to not being naive towards enemies, to the rival being an actually great guy in a non-toxic yet strong rivalry, to the female's (yes plural) are actually strong and useful this anime has what other anime lack.
•Tropes: Has tropes in the beginning but these mostly fade away as the series goes on. The fact is all Shonen genre anime have similar features what sets Black Clover apart is most of the story. It has many unique features from word magic and natural and unnatural mana, to devil powers to anti-magic and arcane stage magic, mana zone, mana method, ultimate magic to how they are used. This anime is not to be quickly judged negatively.
•Animation: Besides the fact that Black Clover has had bad luck in the past (lost 2 outsourced Studios once and their production desk in charge of scheduling) this criticism is often overblown. Usually it's judged against Seasonal anime but Black Clover is weekly so isn't a fair criticism. The animation is amazing at the times needed most and with Studio changes such as new animation Studios to outsource too, new crew and a change of rotation and so on the animation has only gotten much better.
The characters, stories and amazing battles will captivate you. Give it a try and keep going. You simply won't regret it. It's the anime to look out for.
