Even though it is not seen, the thought of one character jumping into space could be disturbing to young viewers.
Many intense sequences of action, with near death situations often occuring.
Episodes can be scary. The cigars of the pharoh has a character who is quite spooky in it.
Sometimes there are disturbing nightmares. In a very frightening dream sequence, an Inca mummy (the one above mentioned) is resurected, climbs down the roof of a house, opens the window, climbs in a throws a crystal ball. Very frightening.
Rather intense.
