Whether you watch this after Breaking Bad or not, this movie is very bland and does not envelop any remote feeling that Breaking Bad had.
Most likely you are an intelligent human being and watch this afterwards as it takes afterwards but in any case:
As somebody else mentioned perfectly, it's practically an extended epilogue episode that merely provides closure to the end of the Breaking Bad television series.
Nothing interesting happens in my opinion; just a minor spare few action scenes with maybe just a couple intense "what's gonna happen" ones. The rest is talking and conflict and the whole load of Jesse being on the run.
It is tiring to watch and is only satisfying because it provides closure to the series but I was disappointed on how boring it is. A single episode of Breaking Bad from any season is better than this entire "movie" on paper.
I only suggest watching this movie for sake of closure but don't expect a whole lot as it is just that, providing closure, nothing more, nothing less.
Some characters pop up again but it feels silent, tiring, and dreadful no matter the case. This could've been done so much better.
A warning for anybody who wants to consider watching, try not to fall asleep after half way to about three-fourths in.
