Each episode includes scenes where characters are in perilous situations. Most children can handle this, though.
It hasn't gone as dark as "The Clone Wars" so far, but it has some really intense moments (I'm writing this after premiere of episode 7).
One episode has large swarms of large bugs attack some characters. May frighten young children.
A young boy watches his mentor get killed. The mentor is shot a few times on screen, and we hear her final scream off screen.
