The lead character Walter White played by Bryan Cranston (Hal from Malcom in the Middle) is a study in balance between humanity and iron resolve.
The other characters are nearly if not as good in their respective roles.
The fact that the story revolves around the manufacture of methamphetamine is almost a side note considering the incredible job done by the cast.
If you like acting elevated to art form, you won't mind that they cook a little LOT of dope.
