Anthony Weiner, for all of us non-US, is an American politician. Some long years ago he was a promise, then he got caught with sending nudes & stuff to women other than his own wife. This documentary probably started with the man thinking it would be a nice idea to let a film crew film his comeback, after the first wave of nudes came out, as a candidate for the Town Hall of NY. And get that glimpse of humanity politicians die for us to see. 
Indeed, we get that, PLUS an extra new batch of nudes which sends his comeback to a dead still. 
I myself am guilty of the pleasure of seeing a politician in full meltdown. 
Trump, don’t keep us waiting, man!
