‘I definitely needed a lie-down after that!’ The most nerve-wracking television episodes ever

Spooks – I Spy Apocalypse (2003)

The show kicks off with the Spooks team restricted while undergoing a drill 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 suspense builds as incoming communications show a disaster happening externally, and escalates as the boss appears to be infected, and the two Home Office officials attempt to leave, pushing the protagonist portrayed by Matthew Macfadyen to opt for either shooting them or permitting their exit and potentially infecting the secure MI5 headquarters. This being Spooks, his decision is predictable.

Threads (1984)

Threads had minimal funding but one of the most frightening programmes I’ve ever seen due to its harsh realism and bleak government data. Watched it about a month ago after seeing the first airing; I used to visit the pub in Sheffield shown in the series that highlighted the truth and the glib matter-of-fact official information that aired. Remaining completely frightening decades on.

Severance – The We We Are from 2022

The season one finale of Severance ranks highly among intense episodes. I was throughout the episode literally perched nervously, straining every sinew with Dylan to hold the switches that kept the Innies on overtime, while yelling at the Innies to get their truths out there. The final climactic moment – “she is living!” – felt like an explosion.

Industry – White Mischief from 2024

Installment five in Industry’s third series caused my heart to pound. I was compelled to halt and rise and exit the space repeatedly owing to the vast degree of the reckless self-harm I was witnessing. Rishi Ramdani faces serious trouble professionally and personally – up to his eyeballs in debt to illegal creditors due to his addictive betting, engaging in dangerous ventures with a bet on sterling which could lose his company millions. Inevitably, he starts a gaming binge, consumes excessive substances and alcohol and wins, loses, wins, is severely assaulted. Each instance you believe things cannot decline more, it worsens. There’s hope of redemption as the installment closes yet he wastes the chance, with horrifying consequences during the season’s final episode. Certainly required a rest afterward!

The 2007 Peep Show episode Holiday

Peep Show itself isn’t necessarily a stressful show. Yet the installment Holiday contains such levels of cringe that it’ll have you standing up for the full show, permeated with worry. The situation intensifies when Jeremy and Mark realize having to lie about the dog they by chance collide with 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 turns out to be!

The West Wing – The Two Cathedrals (2001)

No other viewing has been as gripping compared to my initial viewing the concluding episode of The West Wing’s second season. The episode starts with the aftermath of the death (in a traffic accident) of the president’s confidential aide and escalates to a高潮 involving a Haitian emergency, and the effects of the withheld information of the president’s MS diagnosis, coupled with verification of his aim to seek re-election. Superb programming. Unsurpassed.

Bodyguard – episode one from 2018

The beginning of the UK show Bodyguard, featuring the main character on a train accompanied by his small son, ranks among the most gripping episodes I’ve seen. He spots a Muslim woman going into the loo and knows something is off. The explosive disposal specialists are summoned, enter the train, and endeavor to coax the woman to take off her suicide vest. Anxiety builds to a nearly intolerable level, until, indeed, the vest is disarmed.

Buffy the Vampire Slayer – The Body from 2001

Buffy enters her house to realize her mom has deceased of natural causes, which is the most unusual type of death in this paranormal series. The installment lacks any soundtrack, a sullen tone, and we witness the episode via the perspective of Buffy’s dismay upon uncovering her mother.

The 2007 The Sopranos finale Made in America

The ultimate sequence of the series finale of the show was pants-wettingly tense. And if you watched it when it originally aired, you – at the start – didn’t understand the cause. Tony’s adversaries, actual and perceived, were all vanquished. This seems similar to the first season’s finale, right? “Recall the minor details.” Yet the atmosphere is strangely foreboding. Almost Twin Peaks levels of terror. The family gathers in a diner. Meadow stops the car. Tony sorrowfully notifies Carmela there’s trouble afoot with another member of his team cooperating with the officials. Meadow secures a parking space. Odd persons arrive at the eatery. Look at Tony(?) Meadow is parking. Tony selects a song on the jukebox. Meadow parks. The bell rings, someone enters the restaurant. It cannot be Meadow, she is still parking. Tony looks up. Continue. It ceases. My heart dropped from my mouth roughly 20 minutes after.

The 2016 The Walking Dead episode The Last Day on Earth

I remained awake to view this installment at 2am. It was incredibly tense after the buildup of bad guy Negan discovering the characters, savagely teasing his prey then not knowing who he killed (concluded with a suspenseful moment). The point-of-view shot from the victim and the muffled sounds – oh no! {We then had to wait for season seven|We then needed to await season
