I have covered in previous reviews the contribution Joss Whedon is considered to have made to the modern TV drama (the "long arc") but watching this incredible episode I could help but think that Gilligan and Gould need acknowledgement too.
We already know (Breaking Bad) that their key theme is human foibles. This episode, which seems at first glance to break almost every rule of episodic TV (the star is barely doing a cameo?) is a tour de force not only for Banks' acting but also for way the viewer is hooked off the top and just cannot walk away.
Incredible TV.
And notice how all the episodes for the season end in "O" -- showing off maybe, but they earned the right.
