I think this show is very interesting and fun. You never know what place your going to end up next. Sometimes it can get a little violent, but it's nothing kids can't handle. And the language is very mild. Though there is some sexual dialogue, kids ages 9-10 will be able to understand it. But in season 1, there is one episode parents should be aware about. It's called "The Color of Truth, it takes place in the '50's when Sam leaps into a black man; where blacks were treated horribly back then. And they use the N word a few times (at least on the DVD) and the violence is a little more heavy. But other than that, I think it's a great family Sci-Fi show that kids and adults will love.
