Any fan of the gangster genre knows that goomahs come with the territory. But Tony's tendency to strike up long-term extramarital affairs with some of the world's clingiest/craziest women only served to slow the show's pace down and take screen time away from more interesting subplots. How many more times did we need to see a mistress threatening to kill herself (or succeeding at it) in the wake of being dumped by Tony?
More importantly: We've seen so much of Tony's O-face over the years that it can never be un-etched from our minds. And, oh, how we wish it could!
