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

Spooks – I Spy Apocalypse (2003)

This installment starts with the MI5 agents restricted during a training exercise relating to a hypothetical terrorist attack, monitored by two government representatives. As the situation develops, it seems an actual attack has occurred with a chemical weapon released. The suspense builds as incoming communications show a crisis unfolding beyond their walls, and escalates as the boss appears to be infected, with the two officials trying to exit, pushing the protagonist portrayed by Matthew Macfadyen to decide between shooting them or letting them go and endangering the sterile MI5 environment. Given it’s Spooks, it is unsurprising which one he chooses.

Threads (1984)

The production was inexpensive but one of the most frightening programmes I have ever watched due to its harsh realism and grim official statistics. Watched it about a month ago after seeing the first airing; 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 35 years later.

The 2022 Severance episode The We We Are

The concluding episode of Severance’s debut season deserves a top spot as a tense chapter. I was throughout the episode actually sitting tensely, pushing alongside Dylan to maintain his grip on the controls that kept the Innies on overtime, while shouting to the Innies to get their truths out there. The concluding高潮 – “she is living!” – felt like an explosion.

Industry – White Mischief from 2024

Episode five of the third series of Industry made my pulse quicken. I needed to stop and stand and exit the space repeatedly because of the sheer scale of the wanton self-destruction I observed. Rishi Ramdani faces serious trouble at work and home – buried in financial obligations to loan sharks because of his compulsive gambling, taking such risks on a wager involving sterling which could lose his company millions. Naturally, he embarks on a betting frenzy, consumes excessive substances and alcohol and experiences wins and losses, is brutally attacked. Every time you think the situation cannot deteriorate further, it worsens. There is a chance for salvation as the installment closes but he squanders the opportunity, resulting in dreadful effects in the concluding part of the season. Definitely needed a lie-down after that!

The 2007 Peep Show episode Holiday

Peep Show itself isn’t necessarily a stressful show. But the episode Holiday features such degrees of awkwardness that it’ll have you standing up the whole episode, riddled with anxiety. The situation intensifies as Jeremy and Mark discover needing to deceive regarding the dog they unintentionally hit and following tries to eliminate it. You subsequently use the rest of the installment doubting if it can actually be more terrible than burning, 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 show opens with the fallout of the passing (in a road incident) of the president’s confidential aide and builds to a peak with a crisis in Haiti, and the effects of the withheld information of the president’s MS diagnosis, along with affirmation of his plan to pursue re-election. Superb programming. Unsurpassed.

Bodyguard – episode one from 2018

The start of the British program Bodyguard, with the protagonist on a train accompanied by his small son, is for me one of the most intense episodes ever. He notices a Muslim female heading to the toilet and knows something is off. The bomb squad is alerted, enter the train, and endeavor to coax the woman to take off her suicide vest. Tension escalates to a practically unendurable point, until, indeed, the vest is disarmed.

Buffy the Vampire Slayer – The Body from 2001

Buffy comes into her home to realize her mom has deceased due to natural factors, which is the rarest form of demise in this supernatural show. The episode has no background music, a somber mood, and we view the installment through the lens of Buffy’s shock of discovering her mother.

The 2007 The Sopranos finale Made in America

The concluding moment of the last installment of the show was pants-wettingly tense. And if you viewed it when it first premiered, you – initially – were uncertain of the reason. Tony’s foes, genuine and fictional, had all been defeated. This seems similar to the first season’s finale, right? “Recall the minor details.” However, the vibe is oddly threatening. Nearly Twin Peaks-like fear. The family sit in a restaurant. Meadow finds a parking spot. Tony sadly tells Carmela difficulties are arising with yet another of his crew working with the government. Meadow parks the vehicle. Odd persons arrive at the eatery. Gaze at Tony(?) Meadow continues to park. Tony selects a song on the jukebox. Meadow parks. The bell rings, someone enters the restaurant. It isn’t Meadow, she remains parking. Tony glances upward. Don’t stop. It ceases. My heart sank about 20 minutes later.

The Walking Dead – The Last Day on Earth from 2016

I stayed up to watch this episode during the night. It was extremely gripping after the establishment of antagonist Negan discovering the characters, savagely teasing his prey then not knowing who he killed (ended on a cliffhanger). The point-of-view shot from the victim and the muffled sounds – argh! {We then had to wait for season seven|We then needed to await season
