Re: Breaking Bad Season 4 Premiere Sun 10pm AMC (Spoilers!)
Beyond that, this show has never been "realistic". Most television isn't. I think the word people are actually searching for is "believable," and that's a matter of opinion, but I think everything that's happened has been believable within the framework the show has established.
I've read on different blogs, that the show is actually more "realistic" than you'd think. For instance, the end game with Walt, is not as far out in left field as you'd initially think and similar situations have been documented in "real life". I've also read, that when it comes down to a lot of the details, the writers are pretty accurate with that stuff as well.
