Taken from someone who said it better than I could:What was the point? Other than watching Walt effortlessly defeat everybody in his path?
This was never a show about plot twists. It just wasn't. It was a show about a lot of things, and one of them was seeing Walter come up with a plan and then execute it; from the poison in the first episode right through to the wheelchair bomb. As soon as we saw the M60 in the first episode, it was pretty likely that it was for the nazis. As soon as we saw the mechanism, we knew how it was executed. This is a show that told us Walter was going to get busted 6 episodes before it happened. When we saw Hank and Gomez pinned down, there wasn't a plot twist. They died. We see the plan, we watch the execution. I can't think of any HOLY SHIT, TWIST moments in the show, sometimes things are unexpected (what Walt did to Gretchen and Elliot, the plane crash, poisoning Brock), but there aren't a lot of OMG TWIST. It isn't that kind of show.
Knowing that Walt would make an attempt at redemption, knowing that when it came to it he would save Jesse, knowing that the phone call to Skyler was the last act of Heisenberg, knowing that it was always Walter White, and Heisenberg was just a character he was playing? Those aren't weaknesses in the show, they're strengths. We can figure out what Walt will do because we know the character well enough to put the pieces together. He feels like aperson rather than a means of doling out surprises. I've always maintained that neither the Team Walt nor the Walt Is A Monster people were entirely right, he's a character. He does terrible things for reasons he thinks are right, he has real motivations that you can understand if not agree with. I can look at the last episode, compare it with the performance in the flash forwards and what they tell us about Walt's state of mind and say "yes, that is what Walt would do." It doesn't matter that he didn't fucking drop a shark out of a helicopter onto Gretchen's head and then reveal that he was the new leader of the Aryan Brotherhood. That would have been a Twist. It would have been Unpredictable. It would have been Wrong.
