elf-boy was nervous the first time he saw it, but then he was fine. Now he watches it all the time.
Honestly, I was worried about him watching the Harry Potter POA, what with the dementors. If the kid can handle ringwraiths, he can handle dementors (and vice versa).
I kind of was the same turn of mind: Dementors, Nazgul, Voldemort, Sauron...
It's surprising, how and what these tikes can deal with....
