Breaking Bad Season Four Finale (to the sound of words being eaten)

A little while ago I wrote about how Breaking Bad needed to end and end well. I wrote about the diminishing returns of a once great drama. Look down the page and you'll find the post; it wasn't that long ago. Or don't. Because the last three episodes have turned the ship around. When it came down to it, the resolution was satisfying on almost every level. Walter White's status, someone whose moral compass has always swung wildly while he still insists he knows where he's going, was finally and definitively decided. Jesse also felt like a fitting end to an arc that had threatened to go astray. The humour and tension were as good as they have ever been. What was particularly satisfying was the feel that the earlier episodes which had turned their focus away from White and Jesse and towards Mike and Gus Fring were justified as all the stories came together. There is even a connection to an earlier episode when Walter is spinning the gun in an earlier episode and it points to a plant which at the time you assume it is pointing nowhere. It is only in the final shot of the season that you realise a decision was made. I would like to know what happens to Saul and Mike, but I feel this is the end. Vince Gilliigan has, however, already agreed to another 16 episode season, although he has stated that this will be the end of the series.  Well, he's surprised me before and I will be happy to eat my words all over again. 
They're nutritious.
