I don’t remember any boobs in the last season at all. Maybe once or twice.
It became less as the series progressed. The first few episodes had stuff that looked like scenes for a Bob Guccione movie, probably to generate buzz and draw viewers in. Then just boobs and butts, and some bush in a couple of episodes.
Comparable to some edgier scenes in the 1990s Outer Limits episodes that didn't generate any outrage.
It dwindled to nothing in the last two seasons.
