[€uroMeinke]

I don't know, at age 10 I was certainly familiar with the Faust tale, suicide, etc. but clearly, I'm not the norm.

I think the opera version of Faust (Gounad) is very simplified telling of the tale (like most opera). Now if they were reading Goethe's Faust, with implied infanticide and more mature themes, then perhaps I might go with the age-appropriate critique.
