Tonight, if you didn't already know, AMC airs the final episode of what could possibly my pick for greatest (or "favorite" as I prefer to use) show of all time. If the show ends like Lost did, that placeholder could change, that's why I say "possibly" right now. But at this juncture, if the final episode ends in mediocrity, it can still take that title. Although, it won't. And I'm pretty confident in saying that. There's a reason why its so easy to quickly place Breaking Bad on the highest of pedestals.
Not one episode of Breaking Bad has ever sunk to even being mediocre.
