Sometimes you can watch one episode of TV so good it elevates everything that came before it—or, in some cases, makes everything
after seem a bit flatter. In our picks below, we’re highlighting one of many fantastic episodes from each show or season.
Wanda Maximoff coming to terms with her past, Rue learning to discuss her trauma, and how a detective can lose it all in a moment
are just some of our choices for the Best TV Series Episodes of 2021.

“Previously On” — WandaVision
Written by: Laura Donney | Directed by: Matt Shakman

In the penultimate episode, Agatha takes Wanda on a trip through her past that reveals her upbringing, the Stark bomb that hit her
house, the experiments that unlocked her powers, and the truth about Vision. It features Elizabeth Olsen’s best
performance as Wanda Maximoff, laying bare years of grief that culminate in the loss she suffered during Infinity War.

“Illusions” — Mare of Easttown
Written by: Brad Ingelsby | Directed by: Craig Zobel

A jaw-dropping confession at a wake sets the tone, but the episode does so much more: more clues, more misdirects, and an
unforgettable turn for Colin Zabel. His emotional highs and lows culminate in a life-or-death encounter that leaves Mare—and us—reeling. -
“Episode 8” — Sex Education (Season 3)
Written by: Laurie Nunn, Jodie Mitchell | Directed by: Runyararo Mapfumo

A finale packed with grace notes: Otis waits at the hospital for news on his mum; Cal offers gentle, essential guidance on chest
binding; Erin quietly funds Maeve’s new path; and Chidi safeguards a fragile moment with humor and heart. It’s a warm, generous capstone
that still tees up Season 4. -
“Trouble Don’t Last Always” — Euphoria
Written by & Directed by: Sam Levinson

The holiday special is no throwaway. Nearly the entire episode unfolds at a diner table as Rue speaks with Ali about relapse,
responsibility, and the “why” behind addiction. It’s impeccably written and powerfully performed—a quiet knockout. -
“The Boy from 6B” — Only Murders in the Building
Written by: Steve Martin, John Hoffman | Directed by: Cherien Dabis

A daring, nearly wordless episode from Theo Dimas’s perspective that still pushes the mystery forward and keeps the show’s playful tone.
In a banner year for deaf representation, this 31-minute experiment is unforgettable.
