Too much smoking!
Hardly 3 minutes go by without someone lighting up, good grief Charlie Brown, enough already.
The producers must have been paid big bucks from tobacco co.s for approx. a 40 plus hour ad for chain smoking. There was absolutely no plot requirement for any of the characters to smoke so heavily, it could have been done without any of it. Especially Mirielle, shame for showing young girls such a bad habit, they look to stars as their example.
