This Sunday sees the beginning of the end of an era. Because on Sunday, AMC will premiere the first of the final eight episodes of "Breaking Bad," which over the last five-and-a-bit years has firmly taken its place among the pantheon of TV drama, winning an ever-growing following, rave reviews and fistfuls of awards. For the uninitiated (and really, how many of there can you be now?) the series follows Walter White (Bryan Cranston), a high school chemistry teacher already struggling to make ends meet when he's diagnosed with inoperable lung cancer. Desperate to provide for his family, he teams up with Jesse Pinkman (Aaron Paul), a deadbeat former student, to cook crystal meth. Complications, as you might imagine, ensue.
