1. Hank 'Gets It' Breaking Bad ('Gliding Over All')
So 'The Sopranos' didn't get number one, as that would be too obvious. This means the honour has to go to everybody's favourite cooking show, 'Breaking Bad'. There are actually three cut-to-black moments, all from season five, that I found difficult to choose between. The first is at the end of 'Blood Money', the first episode back from the mid-season break, when Walt confronts Hank in the garage and delivers the best line of the series, "If you don't know who I am, then maybe your best course, would be to tread lightly." Classic. The second great cut-to-black is in 'To'hajiilee', during the standoff in the dessert. There's so much tension building up to this that I was actually shaking when I watched it. The slow motion and sound design during the gunfight is brilliant, and the cut-to-black when Walt is in the car is almost perfect. Almost perfect, because there has to be a number one, and for me, the greatest cut-to-black moment in television history has got to be Hank's 'eureka' moment on the toilet at the end of the mid-season finale. Hank is taking care of business, picks up some light reading material, and finds the old chemistry journal that came up as evidence in the Heisenberg case way back in the series. The initials 'W.W.' on the journal's first page trigger a flashback to the scene when Hank first jokes that 'W.W.' could stand for 'Walter White'. Walt is all like, "You got me!" and Hank is all like, "Cut to black." I'm pretty sure that's the line. Hell, even if it isn't, this was a fantastic cut-to-black cliffhanger which deserves its place at the top of this list.
