‘I absolutely had to rest after that!’ The most nerve-wracking television episodes ever

Spooks – I Spy Apocalypse from 2003

This installment starts with the intelligence unit restricted as part of a simulation relating to a hypothetical terrorist attack, monitored by two government representatives. As events unfold, it seems an actual attack has occurred with a chemical weapon released. The suspense builds as reports reveal a catastrophe taking place outside, and gets worse when the leader seems contaminated, and the government agents endeavor to depart, pushing the protagonist portrayed by Matthew Macfadyen to choose between firing at them or allowing them to leave and potentially infecting the secure MI5 headquarters. Given it’s Spooks, his decision is predictable.

Threads from 1984

Threads was low budget but one of the most frightening programmes I have ever watched owing to its grim authenticity and bleak government data. Saw it not long ago having watched the original; I frequently went to the Sheffield pub shown in the series that highlighted the truth and the glib matter-of-fact official information that were transmitted. Still absolutely terrifying after three and a half decades.

The 2022 Severance episode The We We Are

The season one finale of Severance deserves a top spot among intense episodes. I remained for the whole show actually sitting tensely, straining every sinew with Dylan to maintain his grip on the controls that allowed the Innies to remain active, while screaming at the Innies to reveal their realities. The concluding高潮 – “she is living!” – resembled a outburst.

Industry – White Mischief (2024)

The fifth episode of Industry’s third season had my heart racing. I was compelled to halt and rise and leave the room several times owing to the vast degree of the reckless self-harm I observed. Rishi Ramdani is in major difficulty in his job and domestic life – overwhelmed by debt to illegal creditors due to his addictive betting, assuming hazardous chances on a wager involving sterling that might cost his firm millions. Inevitably, he starts a gaming binge, does tons of drugs and drink and wins, loses, wins, is brutally attacked. Every time you think the situation cannot deteriorate further, it deteriorates. There’s hope of redemption at the end of the episode but he misses the opening, with horrifying consequences in the concluding part of the season. Absolutely had to relax following that!

Peep Show – Holiday (2007)

The series Peep Show isn’t typically anxiety-inducing. But the episode Holiday features such degrees of awkwardness that it will make you rise throughout the entire episode, filled with nervousness. The situation intensifies when Jeremy and Mark realize having to lie about the dog they unintentionally hit and later efforts to get rid of it. You then occupy the remainder of the episode wondering if it might be more awful than cremation, and it is possible!

The West Wing – The Two Cathedrals from 2001

Nothing I have seen has been as tense compared to my initial viewing the season two finale to The West Wing. The episode starts with the aftermath of the death (in a traffic accident) of the president’s personal secretary and reaches a crescendo involving a Haitian emergency, and the fallout from the non-disclosure regarding the president’s multiple sclerosis diagnosis, with confirmation of his intention to pursue re-election. Superb programming. Unequaled.

Bodyguard – episode one (2018)

The start of the British program Bodyguard, with the protagonist on a train alongside his juvenile boy, is for me one of the most intense episodes ever. He observes a woman in Islamic attire going into the loo and senses something is wrong. The bomb squad is alerted, board the train, and endeavor to coax the woman to take off her suicide vest. Anxiety builds to a nearly intolerable level, until yes, the vest is diffused.

The 2001 Buffy episode The Body

Buffy arrives at her residence to find her mum has passed away from natural reasons, which is the most unusual type of death in this supernatural show. The episode has no background music, a gloomy atmosphere, and we view the installment through the lens of Buffy’s astonishment upon finding her mother.

The Sopranos – Made in America (2007)

The concluding moment of the last installment of the series was extremely nerve-wracking. And if you watched it when it originally aired, you – at the start – didn’t understand the cause. Tony’s foes, genuine and fictional, were all overcome. This seems similar to the first season’s finale, right? “Remember the little things.” But the mood is bizarrely ominous. Approaching Twin Peaks-esque horror. The clan sits in an eatery. Meadow parks. Tony sorrowfully notifies Carmela there’s trouble afoot with yet another of his crew cooperating with the officials. Meadow parks the vehicle. Odd persons arrive at the eatery. Stare at Tony(?) Meadow is parking. Tony selects a song on the jukebox. Meadow finds a spot. The bell rings, someone enters the restaurant. Can’t be Meadow, she’s still parking. Tony raises his gaze. Keep going. It halts. My heart sank roughly 20 minutes after.

The Walking Dead – The Last Day on Earth from 2016

I stayed up to watch this episode at 2am. It was incredibly tense after the buildup of bad guy Negan finding the group, cruelly taunting his victims then not knowing who he killed (concluded with a suspenseful moment). The point-of-view shot from the victim and the muted audio – argh! {We then had to wait for season seven|We then needed to await season
