If you watched all seven seasons of The Sopranos, this is like a little refresher course on all the twists, turns, and chicanes of the plot over the years. Since virtually every death was a key plot point, this is an interesting summation of one aspect of the show that alludes to some of the others.
There were some incredible murders in the series, including, finally, most of the characters except Paulie, Tony, Tony's family, and some of the soldiers in Sacrimony/Leotardo and Tony Soprano's crime families.
Stephen Clarke-Willson pointed out that some people felt burned by the way the series ended. If you want to see last moments of the show (and a remixed version), click here. I loved the ending, and don't think I would have changed a thing. The fade to black (without music, for the first time in the show's history) was an incredible way to round things out, although I can see why some people wanted to show tied up with a neat bow.
