It was a very grounded movie of course built in the concrete slabs of New York's Bad Side. The very notion of swinging poses a threat to individuals sturdy in there long term relationship. However that's how it began a complacent experimentation with couples into a daring position of new romance. To me it showed the germlike possesiveness that spread into heavier waves throughout the time-span of wreckage and renewal. All planned by one destroyed businessman - yet love is diverse in it's care and steams of fanatiscism do carry the broken to a position of identity.
Conservatives will know this as a beautiful ephemeral trash building of eternal reclamation.
