It was interesting and fun, but wasn't really the same quality as the rest of season 2 up to this point. It also just feels weirdly placed...the Owl House is much more entertaining in the present, in my opinion. Maybe it's just the entire episode being a flashback that bothered me. If there was a bit more back and forth between the present and the past, I think I would have enjoyed it much more.
Not the worst episode of the show, but probably my least favorite episode in season 2 (which isn't calling it bad, since every episode in season 2 has been phenomenal, until this one)
