I was of total belief that the Sopranos would end next season with the fall of Tony and the family. I was ready to bet that this would come by way of Johnny Sac and Brooklyn. Sac getting nabbed by the Feds was a real bummer as I found his character interesting and that of a true foe/advisary to Tony.
If you watch this season closely, you'll notice (in my opinion) real attempts to portray the family and the business in a truly dark light. When I say dark, I mean having characters do truly shitty things sans the glamour aspect and abandoning any sort of 'street justice'. I guess it seemes like they're showing this kind of lifestyle for what it really is.
Pauly and Chris killing the waiter, Tony B. beating the shit out of the Korean, Adriana obviously and finally Tonys neglect of Carmela and family.
I still have a strong hunch that it will all end with Tony and Co. on the bottom.
