I agree with almost every word she wrote there.

Also, here's a link to a good summary article that puts all of Norm's (pretty excellent) tweets in context:

http://philly.barstoolsports.com/around-barstool/norm-macdonald-poses-theory-that-walter-white-actually-died-in-snowy-car-is-probably-right/

I'm personally hopping on board with this theory 100% because it's the only one, for me, that rises to the level of greatness that I'd seen on the show up until that episode. The finale felt so wildly out of step with the rest of the series (and specifically where all of S5 had been going) that, to me, this is the best way to explain it all.

The other thing I love about this theory is that it means the penultimate episode (which I personally felt after it aired was masterful and possibly the best episode of the series) was the true ending of the Walter White story, and the one that, IMO, is much more fitting and realistic. (The shitty thing about this theory is that Jesse is still a meth slave, but he probably got caught by cops after crashing through the gates anyway...)

But the icing on the cake to me is that the only place in which all the shit that happened in the finale is plausible is in Walt's mind, and for that reason alone, this theory itself is more plausible than the episode at face value. This isn't really a blind shot in the dark, either. I mean, it literally makes a ton of sense to me to read it this way, and IMO really enhances last few episodes.

I'm sure most people won't agree, but whatever.
