It's just a bit of harmless Saturday night family viewing, not a lesson in mythology.
My grandson loved Merlin but his sister would not watch it as it frightened her. She has watched Atlantis without it having any bad effect on her so far.
I just like laughing at the mistakes, although I do not know that much about the legend of Atlantis. I cannot remember it coming into any mythology I taught.
