Yeah, we’ll say it: Breaking Bad, which returns to AMC this Sunday, is the most gripping show on television since The Wire. Which, for some, might be what makes it such a hard sell. The plotting certainly isn’t as intricate or impenetrable, but the mood is similarly hopeless, and that’s not everyone’s idea of a cozy Sunday night on the sofa. But if you haven’t already, give in — because centering a drama around a nebbishy, cancer-stricken chemistry teacher who squanders his family’s (and the audience’s) sympathy by turning into a cold-blooded meth kingpin is no small feat, and it deserves your attention. You may not feel good, but you’ll feel something.
