Five reasons to love "Two Cathedrals"

SPOILER ALERT: Haven't seen The West Wing episode "Two Cathedrals"? Don't read this!

1. Martin Sheen. He delivers a powerhouse performance in the cathedral: he's not bombastic or over-emotional, he simply makes you believe every word he manages to spit out is straight from the heart. He knows when to hold back too though - his restraint in the episode's early scenes is remarkable, hinting that beyond the tough, world-weary exterior, something has to give. The final scenes, as he stands in the rain, before taking the long walk to the press-room, as the strains of "Brothers In Arms" ring out, are worth the price of admission alone: Sheen gives Bartlet an expression that delivers a statement of intent better than any real President ever could.

2. Flashback. Flashbacks are fairly commonplace in 21st century television - from the mythology-building of Lost to the teary sweetness of The Simpsons' high-school years, television shows have been employing them left, right and centre. Rarely to the perfection exemplified here, though - meticulously judged and drawn, the scenes with a younger Jed and Mrs. Landingham are astoundingly heart-warming. So it's from dear old Dolores Bartlet got that inspiration to do something right in the world.

3. Believable "younger" versions of characters. Point two would be null and void without this. All too often, flashback sequences fail to capture the youth of the characters they're supposedly representing. This can be because they didn't find anyone who quite looked the part so settled for the vaguest of resemblance; or (and arguably worse) they used the regular actor, dolloping on heaps of make-up and fashioning an appropriately stereotypical hairdo. "Two Cathedrals" falls victim to neither trope: Jason Widener and Kirsten Nelson are able to portray our beloved characters remarkably believably, without descending into self-parody. Without such talent, this episode wouldn't be half as revered as it is; Widener and Nelson are this show's unsung heroes.

4. Shot composition and direction. Most people take such things for granted; hell, I do too, most of the time. But in episodes like this, you couldn't help but notice just how well the technical department composed the show that wound up on our screens. The final shot stands out, as we look at Bartlet from his right, the American flag waving and rain pounding down; but the scene transitions from flashback to present-day are also worthy of note, as are the stunning shots of the expansive cathedral - a genuine work of art.

5. Writing. The flashback scene where Jed discusses gender inequality with Mrs. Landingham. The scene where a posthumous Mrs. Landingham reminds Jed why he's in office. The scene where Jed curses out God, in both Latin and English. In each one, every word is perfectly judged. Every line fits. Wit is present where needed. So is intense, impactful emotion. Actors, directors and producers are only as good as the material on the page. Thanks heavens that here, that material was genuinely outstanding.
