Quoting Roloccolor, reply 23
I hope and cross my fingers that breaking bad will not end like LOST (i felt cheated and tricked after watching it to the end, i better invested that time into something productive)
 

I can see that..

The Ending, LOST edition:

Walt is dead, has been dead for a long time. He never went into remission, never even considered cooking meth.  He was diagnosed with cancer, lived for a few more months suffering a slow death while refusing treatment, not wanting to leave his family with the crushing debt of medical costs.

The vast majority of the series is a drug induced fantasy, a 'what if' scenario envisioned by a depressed post-Walt Walter Junior who has since developed a meth addiction as a means of coping.

The entire series, this final fantasy, is revealed to be his last moments as Walter Junior overdoses and dies.

All remaining or resulting plot holes and unanswered questions are unexplained or blamed on God, in true LOST fashion.
