There just isn’t a weak season of 'Breaking Bad.' There’s just superior work, a sprint toward evil that turned into a marathon. But like all big-talker shows that bring their heavy cargo in for a rough and breathlessly observed landing, 'Breaking Bad' didn’t quite leave itself enough runway to satisfactorily end some of its better story lines, especially once the chronology gap closed up between the flash-forwards from last year’s episodes and Sunday night’s conclusion. One could easily argue that there was just too much left to do in this one episode.
