there is no nudity at all in both season 1, 2 or 3. Only a very few sex scenes, but you can only see shoulders and up.

In the first episode a woman is wearing a big shirt for a couple of seconds, where you can se some upper tighs, thats all.

Some episodes contain gory images (sliced bodies, etc.) but these are very brief.

The strongest profanity in the TV version are 'bitch' and 'hell', but even these are used rarely.

The DVD/BRay version contains 1 barely audible use of 's**t' and around 5 'gd's across all seasons.
