Westworld
《西部世界》
It's difficult to pick just one episode that illustrates why Westworld earned 22 Emmy nominations, but if we have to choose one, look no further than the Season 1 finale "The Bicameral Mind." In addition to being one of the episodes producers submitted to be considered for a drama series nod, it was also submitted in the directing and lead actress categories. In particular, the episode is a showcase for Wood's performance as Dolores, one of the "hosts" of the mysterious fantasyland.

Feud: Bette and Joan
《宿敌：贝蒂和琼》
Travel back to the 1963 Oscars in the fifth episode of Ryan Murphy's exploration of the feud between Joan Crawford (Lange) and Bette Davis (Sarandon), which also received individual nods in the limited series writing and directing categories. The tension between the dramatized versions of Crawford and Davis is deliciously palpable as Joan schemes to steal the spotlight from Bette on Oscars night, despite not receiving a nomination. Fortunately there isn't as much animosity between Sarandon and Lange as they prepare to face off in the limited series lead actress race on Sunday.

Big Little Lies
《大小谎言》
With five acting nominations under its belt, not to matter nods for writing, directing and series, Big Little Lies is also difficult to narrow down to just one episode. But "Living the Dream," the third installment in the adaptation of Liane Moriarty's novel, coalesces the dynamic among the four women at the heart of the show. In particular, Dern's desperate, Renata and Witherspoon's maddeningly chirpy, and Madeline shine in this episode, which also sets up the show's central mystery and gives us a horrifying glimpse into the marriage of Celeste (Kidman) and Perry (Skarsgard) as they attend couples counseling.

This Is Us
《我们这一天》
Though most of this year's major Emmy nominees require some sort of subscription service, there's no excuse if you've yet to watch This Is Us. NBC's breakout drama hit -- the only broadcast show to earn a drama series nod this year -- was a standout among last season's crop of freshman shows and received 11 nominations total. "Memphis" is pretty universally acknowledged as Season 1's best episode, especially for the chemistry between fictional father-son duo Randall (Brown) and William (Jones). Make sure you have your tissues handy. You'll have to choose a different episode (we'd suggest the pilot) to check out Metz and Ventimiglia's acting chops, but while "Memphis" features a limited perspective, it proves why This Is Us has struck a chord with so many.

The Handmaid's Tale
《使女的故事》
If there's anything that can be considered a "shoo-in" at Sunday's Emmy Awards, it is Elisabeth Moss' well-deserved win in the drama lead actress category for her tour de force performance in the Handmaid's Tale. Spoiler-phobes may not want to jump straight to the Season 1 finale, but not only does it highlight the full range of Moss' excellent performance, it's the episode supporting actress nominee Samira Wiley submitted for consideration as well.

The Night Of
《罪夜之奔》
"The Art of War", the fourth episode of the limited series, ramps up the “friendship” between Naz (Ahmed) and his prison buddy/mentor Freddy (Williams). The Night Of originally aired way back at the beginning of the year, so even for viewers who are looking to get a refresher before the Emmys, this is a great episode to revisit.

Veep
《副总统》
Will the Emmys' love for Veep continue this year? The long-running series is seeking a three-peat in the outstanding comedy category after winning the past two years, and Louis-Dreyfus may take home her sixth trophy for her portrayal of Selina Meyer, a politician whose incompetence makes her endearing. "Groundbreaking" was the Season 6 finale chronicles Selina's political career through the years in flashbacks, as she and her present-day team prepare for the groundbreaking of what will be her library. And it provides the perfect launching pad for what will be the show's seventh and final season.

House of Cards
《纸牌屋》
House of Cards is a long shot to take home any prizes in the acting categories this year. But the Season 5 finale takes Frank and Claire Underwood's (Spacey and Wright) Machiavellian quest for absolute power to new heights -- and proves why Kelly, who was upped from a guest actor to supporting actor this year -- completely deserved his nod

Stranger Things
《怪奇物语》
Arguably the most buzzed-about show of 2017, Netflix's Stranger Things is the runaway favorite to take home the drama series award, especially after it took home the casting award at the Creative Arts Emmys last weekend. Brown could also become the youngest Emmy winner ever as a long-shot contender for drama supporting actress. See what all the fuss over the teen star and the show itself is about with "The Bathtub," the penultimate Season 1 episode in which Brown's Eleven ventures into the "Upside Down" to look for the missing boy Will. In addition to Brown's understated performance, the episode is representative of all the elements of the show that captured viewers' hearts and minds: supernatural creepiness, '80s nostalgia, kids working together to catch some bad guys, and of course, a killer soundtrack.

The Crown
《王冠》
Assassins", the ninth episode of Season 1, features Winston Churchill (Lithgow) announcing his resignation and having his portrait painted for his 80th birthday, as well as Queen Elizabeth (Foy) growing increasingly distant from her husband Philip. In particular, Lithgow embodies Churchill in a way we haven't seen before, in what may prove to be a career-defining performance. Foy, meanwhile, will be looking to take home her second award after winning a Golden Globe this year.
