First of all, I strongly disagree with the majority of reviews here saying that you shouldn't bother seeing this. Honestly, I think that this season shows us more a realistic perspective about Emma and Porsche, as well as Rome and Pick. Unlike the first season which seems to have a hasty storyline and contains many plot-holes, this one presents to its audiences more convincing and concrete plot.
I must say that you would get mixed emotions after watching this one. It was really a roller coaster ride.
I HIGHLY RECOMMEND FOR EVERYONE WHO HAVE WATCHED THE FIRST SEASON TO SEE THIS TOO.
