I think the concentration on AJ was to show ultimately the family is greedy and materilistic. He whined and whined and in the end he gets a posh job, a new beamer and throws all his new found values under the table because that is what his family taught him, to be greedy and materilistic and selfish.
That is the way I took it, life goes on, meadow is still battling the fact that she thinks the feds are giving her dad a hard time because he is italian, instead of the fact that he is a dispicable criminal, then having her tell tony that he inspired her to be a lawyer is a real kick in the pants.
I loved the show, it showed how tony always ends up on top in good shape with some sort of impending doom always on the horizon, carmella continues at all times to be greedy and materialistic, as shown by the look on her face when hunter tells her she is in med school! She was so mad that she was achieving more than meadow. Then it seems as if meadow is pregnant or could be, leading her to possibly be just like carmella in the future, like tony said pop out of few kids etc....
life goes on, doom could be around the corner but in their world everything is fine and materialistic things take precedent. Tony will have new guys around him another member has flipped. In the end its the same ol same ol.
The scene with junior leads me to believe that tony has learned that the whole thing is a big nothing, junior never learned that but Tony sees that it is who he is and he has to keep going.
anyway, I loved it. People will talk about this for years, had it ended with him getting shot in the head it would have been boring and predictable.
