Absolutely! I also watched it thinking it might be too childish, but I ended up glued to the screen. It's truly visually stunning; the mix of anime aesthetics with all the vibrant colors of K-pop gives it incredible energy, and the choreography is superbly done.

I completely agree with you about the message. Beyond the action, that duality between the perfect image they have to project as idols and the (literal and metaphorical) fight against demons adds a touch of depth that's really appreciated.
