Watch this with your sensitive children.
violence is not too bad. Plenty of futuristic robot battles some humans very occasionally die, but this was made in the 60s, so it is caried out in a very mild way (all you see is a lifeless body, with a buise or two). To tell you the truth, I think a tough 6 year old can take the violence, but you should watch this with any kid younger than 8 due to some sad things that happen in just about every episode. you can watch the original one and 2004 version on hulu (nobody under 8 should watch that one at all). 1963: iffy 6-7 2004: iffy 8-9
