A feast for the eyes, that reminds me of the old Dragonball movies that just throw fight after fight at you, but leaves you knowing that it was all a bit pointless since none of it makes any sense next to the canon series. It is more or less exactly what you should be expecting of a Black Clover non-canon anime movie.
It's definitely a spectacle of high production Black Clover which is awesome to see since Black Clover has a great and colorful art style that was just begging for this kind of movie treatment, and the movie doesn't slack off in giving you almost two hours of nonstop action scenes.
It gets to a point where it actually feels like it's too much because the fights just keep going to ridiculous lengths to prolong themselves as power spike after power spike keeps the action going until the credits roll. You get all kinds of the team ups that you've grown to love from Black Clover, including a few you might not expect, as well as all of the ones you knew going into the movie you were going to get.
The story is very shallow, and the movie does not spend a lot of time trying to develop it, or explain it. If you're up to date on the anime's story you know that there's no way any of this makes any sense knowing where all of the characters are in the timeline. This complete detachment makes it seem like all of the stakes the movie tries to make feel important, are all a sham because you know at the end of the day the events in this movie can't ever have happened and nothing serious can actually happen because we have to return to the status quo by the end of the movie because the anime is still ongoing and we have another season to get to eventually. Again, it just reminds me a lot of the way the old Dragonball movies used to be.
Overall, the movie itself is nice visually, if a bit too long considering how shallow it is. But it does give you some fun reasons to be hyped for a new season of Black Clover whenever Pierrot decides to start adapting more of the manga. If this is what Black Clover can look like when it goes all out then we can just hope that we will see something close to this when it has more of the manga to back it up.
