Malcolm in the Middle is a hilarious show that gives "comedy" its true meaning. Things parents should be warned about: there are some sex scenes, especially as the show progresses into the later seasons. These mainly include the control-freak mom, Lois, and the quirky, lovable dad Hal. So, be warned on that. There is also a considerable amount of violence between the brothers Malcolm, Reese and Dewey. Seeing a they are brothers who hate the existence of each other, you have to expect some fallout of the sort. Along with the sex and violence, there is also some smoking and drinking throughout the seven seasons. But overall, I think it's a great show with some great messages about how families should and should not behave.
