Tim Goodman, speculating on the finale of The Sopranos, wrote:
And Tony's fate is still undecided.
Is that such a bad thing? The static, Chase-esque, unrequited climax always seemed romantic -- have the series end with nothing happening, as if the camera shut off while filming, as if Tony and his two families went on with their lives, but our little glimpse ended.
Goodman goes on to change speculate on a number of other possible endings, but if he'd just ended his article there, that would be a pretty good call.
That will go down as one of the more famous cuts to black in editing history. That entire last scene was just an editing tour de force.
