Apart from the usual drama, there is quite a number of sex scenes in the series, but they are not that revealing, which is not really surprising, because the networks have some strict rules in regards to sex and nudeness. But the rules for depiction of violence are obviously not as rigid; the show does not contain that many scenes with violence, but those few scenes are always really bloody. But the series also contains some censorship, which can be seen at the episode "The Consummation (S01E13). The channel has provided an uncensored director's cut on its homepage, which differs in two sex scenes in comparison to the TV version. These two scenes obviously were too explicit for a TV broadcast, so The CW had to make some cuts. A detailed comparison between both versions with pictures can be found here.
