I love this show. I think it is good for 11-year-olds and over, or maybe 11 year-olds close to the age of 12. I think that the season 8 should not be watched, because of violence. That may be the only violent season in Smallville. There is normal hero violence, like punching and throwing, but not too much. I agree to SmallvilleGrl that Season 5 isn't age appropriate either. Anything else is great.
