Also try "Torchwood", a post-watershed (ie not for kids) spin-off of Dr Who. The creators of the "new" Dr Who wanted to create another series that was more adult themed and less of a family show. The word "Torchwood" is actually an anagram of "Doctor Who". Torchwood is an agency that occasionally appeared in Dr Who that save the world from alien invasion. It's like a British version of the X-Files (X-Files is very adult themed. It does not have much inappropriate content, it simply does not appeal to children. Torchwood is the same.)
NOTE: As the show progresses, it becomes more and more raunchy. The first season isn't bad, but the second season is quite vulgar - definitely NOT for children.
