It's often a big maligned 'Studio 60' for various reasons, and for being the only Aaron Sorkin penned show to not get a second series (The Newsroom went for three, but that doesn't mean it was much good) but this episode really shows the quality of the writing and the cast involved.
Flashing back to just after 9/11 shows us how the characters dealt with the crisis, and how a comedy show carries on in the face of tragedy.
I thought Steven Weber as ever was fab as Jack Rudolph, and there were some lovely moments between Bradley Whitford's Danny and Amanda Peet's Jordan too.
The final sequence set to 'Have a little faith in me' by John Hiatt was brilliant, and topped off a fabulous episode of the show.
