The reason this rude, shallow, insulting person is apparently successful--underline 'apparently'--with her clients is because by definition, when you resort to a matchmaker, you are ready to accept whomever they throw at you. So that doesn't say a whole lot in favor of her vaunted track record.
There is almost nothing said on this show in favor of those lost qualities such as charm and intellect. It's all about how to look good, not be stupid in a restaurant, and get them to call you next week. In other words, it's about the conceit of one person, instead of the deeper interests of both. The creation of actual positive feelings, as opposed to superficial impressions, is not only discarded, it's actually ridiculed. No wonder there are so many bad relationships today. If this is what's out there, please, consider celibacy.
