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

The 2003 Spooks episode I Spy Apocalypse

The show kicks off with the MI5 agents locked down as part of a simulation about a potential terror incident, supervised by two Home Office agents. As events unfold, it seems an actual attack has occurred and a chemical agent deployed. The tension ratchets up as messages indicate a disaster happening externally, and gets worse as the superior shows signs of exposure, with the two officials trying to exit, forcing Matthew Macfadyen’s character to decide between shooting them or permitting their exit and endangering the sterile MI5 environment. As this is Spooks, it is unsurprising which one he chooses.

The 1984 production Threads

Threads was low budget yet among the scariest shows I have viewed due to its harsh realism and grim official statistics. Saw it not long ago following the initial broadcast; I used to visit the pub in Sheffield from the programme which underscored the actuality and the offhand factual official statements which was broadcast. Still absolutely terrifying 35 years later.

Severance – The We We Are from 2022

The concluding episode of Severance’s debut season ranks highly among intense episodes. I spent the entire episode quite literally on the edge of my seat, exerting with Dylan to maintain his grip on the controls that allowed the Innies to remain active, 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

The fifth episode of Industry’s third season caused my heart to pound. I had to pause and get up and exit the space repeatedly due to the immense extent of the wanton self-destruction I saw. Rishi Ramdani faces serious trouble professionally and personally – buried in financial obligations from unscrupulous lenders 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, uses copious drugs and alcohol and wins, loses, wins, is brutally attacked. Every time you think the situation cannot deteriorate further, it does. Redemption seems possible as the installment closes but he misses the opening, resulting in dreadful effects during the season’s final episode. Definitely needed a lie-down after that!

Peep Show – Holiday from 2007

Peep Show itself isn’t necessarily a stressful show. Yet the installment Holiday features such degrees of awkwardness that it will make you rise for the full show, riddled with anxiety. The tension escalates once Jeremy and Mark find themselves being compelled to falsify about the canine they by chance collide with and later efforts to get rid of it. You then occupy the remainder of the episode questioning whether it truly can be worse than incineration, and it can be!

The West Wing – The Two Cathedrals (2001)

Nothing I have seen has been as tense as when I first saw the second season finale of The West Wing. The episode starts with the aftermath of the demise (in a car crash) of the president’s personal secretary and escalates to a高潮 with a crisis in Haiti, and the repercussions of the secrecy about the president’s MS condition, along with affirmation of his plan to pursue re-election. Excellent TV. Never bettered.

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 spots a Muslim woman entering the restroom and senses something is wrong. The bomb squad is alerted, board the train, and try to persuade the woman to take off her suicide vest. Tension escalates 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 realize her mom has deceased due to natural factors, which is the most unusual type of death in this supernatural show. The episode has no background music, a sullen tone, and we see the episode through the experience of Buffy’s shock of discovering her mother.

The Sopranos – Made in America from 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 first – weren’t sure why. Tony’s enemies, real and imagined, had all been defeated. Surely this has the feel of the season one ending? “Recall the minor details.” However, the vibe is oddly threatening. Nearly Twin Peaks-like fear. The clan sits in an eatery. Meadow finds a parking spot. Tony gloomily informs Carmela there’s trouble afoot with yet another of his crew collaborating with the authorities. Meadow parks. Unfamiliar individuals come into the diner. Look at Tony(?) Meadow parks. Tony plays a track on the music machine. Meadow parks her car. The bell rings, someone enters the restaurant. It isn’t Meadow, she remains parking. Tony looks up. Don’t stop. 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 so intense following the introduction of villain Negan locating the survivors, mercilessly mocking his targets and then leaving the victim unknown (finished with an unresolved situation). The first-person perspective of the victim and the muffled sounds – argh! {We then had to wait for season seven|We then needed to await season
