It's too obvious that the guy in the Members Only jacket went to the toilet like Michael Corleone and then whacked Tony. I think that was the ultimate red herring. The point was that when Michael did it, the last thing in the world that it could be accused of being was obvious. If you think that the likeliest guy in the place doing what the unlikeliest guy in the place did is some kind of homage, then to me you're barking up the wrong tree.
That's not to say I liked the ending, I thought it was less intelligent and clear than everything that went before it. Chase was trying too hard to be mysterious. The beauty of using symbolism is that you only need to reference one thing, referencing ten misses the point.
Still thought it was a magnificent series, though. Second only to Mad Men.
