No, you're not the only one that feels no attraction to mafia hype. These people make me embarrassed to admit I'm part Italian. To me they've always seemed ignorant, lazy (as in becoming a career criminal is easier than getting an education and doing something beneficial with your life) and obnoxious. As for taking care of their own, Henry Hill's (Goodfellas) children recently published a book about how untrue that is.
That said, I am taking an interest in this book, at least so far. It seems like she's going to portray it for the seedy and unhappy life it is rather than some Hollywood fantasy. I think her quote that in real life it's all about the money and that loyalty and respect are for the movies is very insightful.
