‘I truly required a break after that!’ The most nerve-wracking TV episodes ever

Spooks – I Spy Apocalypse from 2003

This installment starts with the Spooks team locked down during a training exercise about a potential terror incident, overseen by two Home Office officials. As the situation develops, it appears that there really has been an attack with a chemical weapon released. The tension ratchets up as messages indicate a crisis unfolding beyond their walls, and escalates when the leader seems contaminated, with the two officials trying to exit, forcing Matthew Macfadyen’s character to decide between shooting them or allowing them to leave and endangering the sterile MI5 environment. As this is Spooks, his decision is predictable.

Threads from 1984

Threads was low budget but one of the most frightening programmes I’ve ever seen because of the stark reality and grim official statistics. Watched it about a month ago after seeing the first airing; I frequently went to the Sheffield pub featured in the show that highlighted the truth and the glib matter-of-fact official information which was broadcast. Remaining completely frightening 35 years later.

Severance – The We We Are (2022)

The first season finale of Severance deserves a top spot among intense episodes. I was throughout the episode literally perched nervously, pushing alongside Dylan to keep his hands on the levers that allowed the Innies to remain active, while screaming at the Innies to reveal their realities. The ultimate peak – “she is living!” – resembled a outburst.

Industry – White Mischief from 2024

The fifth episode of Industry’s third season caused my heart to pound. I needed to stop and stand and exit the space repeatedly owing to the vast degree of the wanton self-destruction I observed. Rishi Ramdani faces serious trouble in his job and domestic life – up to his eyeballs in debt from unscrupulous lenders because of his compulsive gambling, assuming hazardous chances with a bet on sterling that might cost his firm millions. So of course, he goes on a gambling spree, uses copious drugs and alcohol and wins, loses, wins, gets beaten to a pulp. Every time you think it can’t get any worse, it worsens. There is a chance for salvation as the installment closes but he misses the opening, leading to terrible outcomes during the season’s final episode. Absolutely had to relax following that!

Peep Show – Holiday (2007)

The series Peep Show isn’t typically anxiety-inducing. But the episode Holiday includes such amounts of embarrassment that it will make you rise throughout the entire episode, permeated with worry. It all ramps up when Jeremy and Mark realize having to lie about the dog they unintentionally hit and subsequent attempts to dispose of it. You then spend the rest of the episode questioning whether it truly can be worse than incineration, and it can be!

The West Wing – The Two Cathedrals from 2001

No other viewing has been as gripping than the first time I watched the concluding episode of The West Wing’s second season. The episode starts with the aftermath of the passing (in a road incident) of the president’s personal secretary and builds to a peak with a situation in Haiti, and the fallout from the non-disclosure about the president’s MS condition, along with affirmation of his plan to seek re-election. Superb programming. Never bettered.

Bodyguard – episode one from 2018

The opening of the British series Bodyguard, with the hero aboard a train alongside his juvenile boy, is personally a top tense installment. He spots a Muslim woman heading to the toilet and senses something is wrong. The bomb squad is alerted, get on the train, and endeavor to coax the woman to discard her bomb jacket. Anxiety builds to a nearly intolerable level, until yes, the vest is diffused.

Buffy the Vampire Slayer – The Body from 2001

Buffy arrives at her residence to discover her mother has died due to natural factors, which is the rarest form of demise in this supernatural show. The episode has no background music, a sullen tone, and we view the installment through the lens of Buffy’s dismay upon uncovering her mother.

The Sopranos – Made in America (2007)

The ultimate sequence of the series finale of the program was incredibly anxious. And for those who saw it during its initial broadcast, you – initially – were uncertain of the reason. Tony’s enemies, real and imagined, were all overcome. Surely this has the feel of the season one ending? “Think about the small elements.” But the mood is bizarrely ominous. Nearly Twin Peaks-like fear. The family gathers in a diner. Meadow parks. Tony sadly tells Carmela difficulties are arising with yet another of his crew collaborating with the authorities. Meadow secures a parking space. Odd persons arrive at the eatery. Stare at Tony(?) Meadow continues to park. Tony plays a track on the music machine. Meadow parks her car. The bell sounds, an individual enters. Can’t be Meadow, she’s still parking. Tony raises his gaze. Keep going. It ceases. My spirit fell around 20 minutes subsequently.

The Walking Dead – The Last Day on Earth (2016)

I kept late hours to see this show in the early morning. It was incredibly tense after the buildup of bad guy Negan finding the group, mercilessly mocking his targets and then leaving the victim unknown (ended on a cliffhanger). The point-of-view shot from the victim and the muted audio – oh no! {We then had to wait for season seven|We then needed to await season
