They failed to make Mistletainn look like an actual psychopath. Instead, they just made her seem like a weird ass kid, and the fight got me bored. The only thing that kept me watching this episode was the plot. Don't forget about the power inconsistencies, this isn't the studio's fault, but rather an issue with the manga itself, which seems to lack a well defined power system. By the end of the episode, the plot is enjoyable, but the action was kind of meh. I have high hopes for the next episode, especially since it's the finale.
