‘I truly required a break after that!’ Your most nerve-wracking episodes of TV you’ve seen

Spooks – I Spy Apocalypse (2003)

The episode begins with the Spooks team confined as part of a simulation concerning a fictional terrorist event, overseen by two Home Office officials. As things progress, it seems an actual attack has occurred with a chemical weapon released. The tension ratchets up as reports reveal a catastrophe taking place outside, and gets worse when the leader seems contaminated, with the two officials trying to exit, pushing the protagonist portrayed by Matthew Macfadyen to choose between firing at them or letting them go and potentially infecting the secure MI5 headquarters. As this is Spooks, his decision is predictable.

Threads (1984)

The production was inexpensive yet among the scariest shows I have viewed owing to its grim authenticity and grim official statistics. Watched it about a month ago following the initial broadcast; I used to visit the pub in Sheffield from the programme which emphasised the reality and the glib matter-of-fact official information which was broadcast. Remaining completely frightening decades on.

Severance – The We We Are from 2022

The concluding episode of Severance’s debut season has to be right up there in terms of gripping installments. I remained for the whole show actually sitting tensely, straining every sinew with Dylan to keep his hands on the levers that sustained the Innies’ extended time, while shouting to the Innies to disclose their facts. The ultimate peak – “she survives!” – felt like an explosion.

Industry – White Mischief (2024)

The fifth episode of Industry’s third season made my pulse quicken. I needed to stop and stand and depart the area multiple times owing to the vast degree of the wanton self-destruction I saw. Rishi Ramdani is in deep shit in his job and domestic life – up to his eyeballs in debt to illegal creditors because of his compulsive gambling, assuming hazardous chances with a gamble on the pound that might cost his firm millions. So of course, he goes on a gambling spree, does tons of drugs and drink and experiences wins and losses, gets beaten to a pulp. Every time you think it can’t get any worse, it worsens. There is a chance for salvation by the episode’s conclusion but he squanders the opportunity, resulting in dreadful effects during the season’s final episode. Certainly required a rest afterward!

Peep Show – Holiday from 2007

Peep Show is not inherently a tense series. Yet the installment Holiday contains such levels of cringe that it can cause you to stand for the full show, permeated with worry. The tension escalates once Jeremy and Mark find themselves being compelled to falsify about the canine they unintentionally hit and subsequent attempts to dispose of it. You subsequently use the rest of the installment doubting if it can actually be more terrible than burning, and it is possible!

The 2001 The West Wing episode The Two Cathedrals

Nothing I have seen has been as tense compared to my initial viewing the concluding episode of The West Wing’s second season. The installment begins with the consequences of the demise (in a car crash) of the president’s personal secretary and escalates to a高潮 with a situation in Haiti, and the fallout from the non-disclosure about the president’s MS condition, with confirmation of his intention to pursue re-election. Excellent TV. Unsurpassed.

The 2018 Bodyguard premiere episode

The beginning of the UK show Bodyguard, with the hero aboard a train accompanied by his small son, is personally a top tense installment. He notices a Muslim female entering the restroom and realizes something is amiss. The explosive disposal specialists are summoned, get on the train, and try to persuade the woman to remove her explosive vest. Anxiety builds to an almost unbearable degree, until yes, the vest is diffused.

Buffy the Vampire Slayer – The Body from 2001

Buffy enters her house to discover her mother has died due to natural factors, which is the most unusual type of death in this mystical program. The show features no musical score, a gloomy atmosphere, and we witness the episode via the perspective of Buffy’s shock of discovering her mother.

The Sopranos – Made in America from 2007

The ultimate sequence of the series finale of the show was pants-wettingly tense. And for those who saw it during its initial broadcast, you – at first – weren’t sure why. Tony’s adversaries, actual and perceived, had all been defeated. Doesn’t this resemble the season one conclusion? “Remember the little things.” However, the vibe is oddly threatening. Almost Twin Peaks levels of terror. The clan sits in an eatery. Meadow stops the car. Tony sorrowfully notifies Carmela there’s trouble afoot with yet another of his crew cooperating with the officials. Meadow parks. Odd persons arrive at the eatery. Look at Tony(?) Meadow is parking. Tony plays a track on the music machine. Meadow parks. The door chimes, a person comes in. It isn’t Meadow, she remains parking. Tony raises his gaze. Continue. It stops. My heart dropped from my mouth around 20 minutes subsequently.

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 locating the survivors, cruelly taunting his victims then not knowing who he killed (ended on a cliffhanger). The victim’s POV shot and the subdued noises – argh! {We then had to wait for season seven|We then needed to await season
