I purchased this
Clash Of The Gods dvd for my 8 eight year old son. He has read all the Percy Jackson novels and is now heavily into greek mythology. Of course this otherwise excellent documentary was not made for children. It depicts rather violent scenes and it's descriptions of heros, monsters and demigods fueled my sons imagination. It is an excellent documentary, researching the possible origins for myths, but to be viewed with caution when children are around.
My son still loved
Clash Of The Gods dvd set, and it did trigger continuative discussions in our family!
