The character development of Walter H White, being a High School Chemistry teacher to the Drug lord HEISENBERG and a careless student JESS PNKMN transforms from a low level street drug dealer to claiming strength almost as Heisenberg. It develops the characters in a terrific way.
And maintains a steady level of consistency throughout its 62 episodes is not a joke...
And the dedication of Bryan Cranston Having french beard style and Shaved head most of the time and also Jesse transformation is can't described in words
So many series's acclaims so much response and fame during their initial seasons... And they take advantage of that as tend to seasons to seasons and episodes to episodes but failed to give even a satisfactory ending, and their writings of their final seasons was totally dumb.
