Well, I enjoyed watching it. It was a well played vignette, albeit a rather superfluous piece of storytelling. It kind of reminded me of a feature length version of something like a tv show webisode. You know, one of those things that wiggles around in the gaps of our main story?
The narrative really didn't need this. The final shot of Jesse wildly driving away, in the last episode, spoke visually to all of this already, and was rather brilliant in that it did so with just that. He's free. Every last detail about how he became free? not as important imho, as the journey to him being finally free.
You didn't need to see Walter's death play out, & you didn't need to see Jesse's life play out. Walter had a well deserved death coming, & Jesse had a well deserved life coming. Walter went bad, & Jesse went good. Spelling it out like this kind of syphons off a bit of the dramatic impact the show left is with imho
Plus... they waited too long. Plemons does not look like he did on the show... anymore, but it gets a passing grade for entertainment value, & who can complain about getting to see Robert Forrester one last time?
