Seriously. We haven't even seen the first episode of this; we have no idea how dark it'll be. The Clone Wars was a pretty light series and even it had some very dark moments.

Humdingers has the right mindset here.

You may be right. I could be suffering from perception bias. I've been trying to think of any Disney animations and movies that have explored dark themes or had dark moments. I keep coming up blank. They do have a reputation for presenting the cute and fluffy in a mostly lighthearted, non-threatening, and non-scary way. They also have a habit of sanitizing out the violence. And if the characters break into song they totally lose me. I am sure there must be exceptions. Maybe others can enlighten me with some examples.
