Brazilian Zouk, which is itself a highly technical dance, and I can attest that sensual moves are not at all easy to lead.
I don’t know what is the difference between Brazilian Zouk and the Zouk that is normally danced at SBK. The zouk socials which I have seen in the USA and Europe:
- the music is utterly boring and monotonous
- women really love to dance zouk
- most guys I know aren’t attracted to zouk
- there is nothing much to lead in zouk. Most things are done by the lady. Zouk is all about shaping by the lady. Yeah the man can sway here and there. A lady can do all those things without a man too.
- zouk has same issue as BS. Too much of manufactured sensuality.
Whether it is zouk or BS, men are only there like a support beam

it is boring and uninteresting.
Perhaps it's everything that goes with the BS scene that annoys salseros.
No. It is about BS for long being a parasite on the salsa. Personally I find BS music utterly crap and all BS moves/dancing to be like zouk at best (which means crappy) and cringey at worst.
I like bachata music and I have danced a lot of bachata. It was not BS. But it was far more sensual and at times more risqué than most what you see in BS.
But the moves themselves are legitimate dance techniques that can look very nice if danced appropriately.
All those moves existed in salsa, bachata, zouk before BS came into existence. Mostly on the stage and performance side.
BS took a certain moves and created a whole dance out of it. That’s like a new dance taking spins from salsa and WCS and creating a new dance which is all about spins. If you know anything about WCS, there are different styling put into spins (some only use it in salsa during performance).
P.S. - It is not easy on a forum dedicated to salsa, find much appreciation for BS.
