my review pretty much reinforces what i see most people on here feel. I really enjoyed danmachi with bell and i was excited to hear about sword oratoria, while it wasn't a new season it was said to be from Aiz's point of view. I fully believe going into it thinking that was one of the reasons I didn't enjoy it as much. While some of the moments with Aiz were enjoyable (for me at least), they were few and far between. Instead this story focuses on Lefiya, a girl in her familia who is obsessed with her and frankly, is down right annoying.
Sword Oratoria is worth the watch is you're interested in learning more about the Danmachi setting but before you start be warned, this isn't "The Ais Show" most fans were hoping for.
