The witch or the other?
The witch one wasn't super duper bad but it was less interesting than most, the plot was predictably basic, the heroes don't do much because it's more about another character, in fact they almost don't matter at all, parts of it are just a rehash of information we already know, which would be fine if this wasn't episode 7, It had one really easily noticeable animation error as well. But it wasn't all bad, it still looked great for the most part and the magic stuff was pretty cool. The execution just wasn't on par with the rest of the series and failed to really pull me in.
The other one I haven't seen yet but from what I hear they talk. This show has had absolutely no talking in it so far so it's pretty strange to suddenly have words being said, seems like they are moving away from the original premise a bit as well.
