I absolutely adored the first two episodes of S4. In fact, I thought this season was off to the strongest start since S1. But the third episode ("Open House") was like Don Salamanca's watery deuce.
I just don't care about Marie or her kleptomania. I also find it ridiculous that Skyler would risk faking an EPA inspection, when one phone call to the agency would reveal her deception. All the moreso after her lecture to Walt about not taking unnecessary risks.
It just didn't work for me. At all.
