^ to be fair Aquors was pretty dramatic and much more serious compared to Muse. And the current live-action drama is also has plenty of drama, though it's no where near Ave Mujica's level.
honestly I love how Love Live does drama much more, because when something bad happens: Honoka collapsing, Aquors losing their school regardless, Kanon in the first few episodes of Superstars,... we can clearly feel the despair and loss in the characters, but we know things will turn out fine in the end because it's Love Live, and I find that really reassuring.
