I have to tell you that I have never seen The Sopranos, but in reading the press this morning, everyone was surprised and/or upset by the ending of this series. Here is the Washington Post point of view this morning.
So, in case you missed it, here are the final five minutes of the episode. Watch it now before YouTube is forced to remove it from their database. Personally, I don't get the ending, but, I guess that's how the writer/creator wanted to leave it.
Update: After a couple of hours since the original post, the above video had already been "deleted by the user." I've also seen this message today: "This video is no longer available due to a copyright claim by Home Box Office, Inc." I did manage to find found another YouTube link (for now). If you haven't seen it, click here before this is deleted.
