Well...I'm still going to miss it. In that sense I'm glad that the series was open ended. I was just disappointed in the overall quality of the show - and that's been for quite a while, 'tho for me, even a bad Sopranos is entertaining.
As an aside - the show was derailed back when Nancy Marchand died. I think Chase had a story ark that was based to a large extent on that character. Every thing had to be rethought and Chase lost some enthusiasm at that point.
I've been watching I, Claudius on dvd. Livia, the wife of Augustus Caesar, is portrayed as a murderous schemer. I think it is no accident that Tony's mother was named Livia.
