My grandson, aged 7 has now got all this series (except for Vol 9 - which is so far unavailable) and they are currently his favourite DVDs. Vol. 5 is a recent acquisition and it is getting as much playtime as all the others. Even his older sister who is 9 years old deigns to sit and watch them when they are playing!
All the Batman Brave and the Bold DVD series that I have purchased have been excellent and have entertained the children for hours. All the characters and stories are well thought out and wonderfully represented in a children friendly way without been too dark as some of the adult versions of the characters have a tendency to be.
