The AP's Frazier Moore summed it up thusly:
Having started strong last March with the near-fatal shooting of mob boss Tony Soprano by his senile Uncle Junior, the sixth season of this HBO drama seemed to wilt, week to week, in synch with Tony’s recovery.
The inevitable murder of Soprano captain Vito Spatafore -- offed by fellow mobsters for being gay -- had taken place in the next-to-last episode. But proving somewhat anticlimactic, it only whetted the audience’s appetite for a decisive dramatic finish to the 12-episode season.
That didn’t happen.
