^Reading the Swing thread on kasidie.com -where they recruited most of the cast- people were saying they wanted less emphasis on the sex, more about showing what the "lifestyle" is about, showing what the newbie couple is going through in their minds as they begin.
Seeing these new episodes I'm now getting the impression the producers did get swayed by those swingers into turning this show into more of a propaganda piece for swinging, rather than quality jerk-off material. Which would be fine if the show was primarily viewed by couples curious about getting into swinging, but I seriously doubt that.
I also miss the kitschy red room theme music from the first 2 seasons.
