This show's second season premiers tomorrow night at 10 on AMC. If you have not seen it, you really should give it a try. It's imaginative, dark, humorous, serious, and heartbreaking. I stumbled upon a write-up about it last year and had to watch it. Here is a synopsis of the show from the AMC website:
"Breaking Bad follows protagonist Walter White (Bryan Cranston), a chemistry teacher who lives in New Mexico with his wife (Anna Gunn) and teenage son (RJ Mitte) who has cerebral palsy. White is diagnosed with Stage III cancer and given a prognosis of two years left to live. With a new sense of fearlessness based on his medical prognosis, and a desire to secure his family's financial security, White chooses to enter a dangerous world of drugs and crime and ascends to power in this world. The series explores how a fatal diagnosis such as White's releases a typical man from the daily concerns and constraints of normal society and follows his transformation from mild family man to a kingpin of the drug trade."
And here's a short video that recaps the first season's first episode:
