Yea, it's not exactly a detective story. It's about an average high school Chemistry teacher, who's a chemistry genius, that gets diagnosed with Cancer and decides to cook meth to pay the Chemo bills and provide for his family. The writing is TOP NOTCH. I swear every episode of every season is gold.
Yeeah, after knowing the next series starts filming in 2013 is the most depressing thing ever. We're only half-way in 2012 too. S02E03 was probably the biggest cliffhanger I've ever seen in movies and television series.
