Walt White's old adversary Mike Ehrmantraut put it best: "You know how they say 'it's been a pleasure'? It hasn't." After five agonizing seasons, Breaking Bad finally reached Miller Time with last night's finale caper, using Badfinger's bleakly romantic "Baby Blue" as a last word, as Walt White tears down the remnants of the drug empire he built with his own bad fingers. "Baby Blue" is a brutally sad love song, sung to a woman who's already given up and walked away. But it's the perfect farewell for Walt – a husband who looked inside himself for monsters and had no trouble finding them.
