‘I truly required a break after that!’ Your most intense television episodes of all time

Spooks – I Spy Apocalypse from 2003

The episode begins with the MI5 agents locked down during a training exercise relating to a hypothetical terrorist attack, overseen by two Home Office officials. As the situation develops, it appears that there really has been an attack and a chemical weapon has been unleashed. The suspense builds as incoming communications show a crisis unfolding beyond their walls, and escalates as the superior shows signs of exposure, with the two officials trying to exit, pushing the protagonist portrayed by Matthew Macfadyen to decide between shooting them or letting them go and risking contaminating the sealed MI5 offices. This being Spooks, it is unsurprising which one he chooses.

Threads (1984)

Threads was low budget but arguably the most terrifying series 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 often attended the bar in Sheffield from the programme which emphasised the reality and the casual, straightforward government details which was broadcast. Continuing to be utterly horrifying after three and a half decades.

Severance – The We We Are from 2022

The season one finale of Severance ranks highly in terms of gripping installments. I spent the entire episode actually sitting tensely, exerting with Dylan to keep his hands on the levers that sustained the Innies’ extended time, while screaming at the Innies to get their truths out there. The concluding高潮 – “she survives!” – felt like an explosion.

The 2024 Industry episode White Mischief

Installment five in Industry’s third series made my pulse quicken. I needed to stop and stand and depart the area multiple times due to the immense extent of the deliberate ruin I observed. Rishi Ramdani is in major difficulty in his job and domestic life – overwhelmed by debt to illegal creditors owing to his uncontrollable gaming, engaging in dangerous ventures on a wager involving sterling which could lose his company millions. Inevitably, he starts a gaming binge, uses copious drugs and alcohol and experiences wins and losses, is brutally attacked. Every time you think it can’t get any worse, it deteriorates. There’s hope of redemption by the episode’s conclusion yet he wastes the chance, leading to terrible outcomes in the concluding part of the season. Definitely needed a lie-down after that!

Peep Show – Holiday (2007)

Peep Show itself isn’t necessarily a stressful show. However, the Holiday episode contains such levels of cringe that it will make you rise the whole episode, permeated with worry. The tension escalates as Jeremy and Mark discover having to lie about the dog they unintentionally hit and subsequent attempts to dispose of it. You subsequently use the rest of the installment wondering if it might be more awful than cremation, and it can be!

The West Wing – The Two Cathedrals (2001)

Nothing I have seen has been as tense than the first time I watched the second season finale of The West Wing. 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, coupled with verification of his aim to run for another term. Superb programming. Never bettered.

The 2018 Bodyguard premiere episode

The beginning of the UK show Bodyguard, with the hero aboard a train accompanied by his small son, 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 diffuser experts are called, get on the train, and attempt to convince the woman to take off her suicide vest. Anxiety builds to a practically unendurable point, until, finally, the vest is neutralized.

Buffy the Vampire Slayer – The Body from 2001

Buffy comes into her home to discover her mother has died from natural reasons, which is the rarest form of demise in this paranormal series. The installment lacks any soundtrack, a sullen tone, and we witness the episode via the perspective of Buffy’s shock of discovering 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 – at the start – didn’t understand the cause. Tony’s adversaries, actual and perceived, 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 family gathers in a diner. Meadow parks. Tony sadly tells Carmela difficulties are arising with an additional associate cooperating with the officials. Meadow parks the vehicle. Unfamiliar individuals come into the diner. Look at Tony(?) Meadow continues to park. Tony puts a record on the jukebox. Meadow finds a spot. The bell rings, someone enters the restaurant. It isn’t Meadow, she remains parking. Tony raises his gaze. Don’t stop. It halts. My spirit fell roughly 20 minutes after.

The Walking Dead – The Last Day on Earth from 2016

I remained awake to view this installment in the early morning. It was so intense after the buildup of bad guy Negan locating the survivors, savagely teasing his prey and then keeping the death a mystery (ended on a cliffhanger). The victim’s POV shot and the muted audio – ugh! {We then had to wait for season seven|We then needed to await season
