‘I truly required a break after that!’ The most nerve-wracking television episodes you’ve seen

Spooks – I Spy Apocalypse (2003)

The show kicks off with the Spooks team locked down while undergoing a drill concerning a fictional terrorist event, supervised by two Home Office agents. As the situation develops, it seems an actual attack has occurred with a chemical weapon released. The tension ratchets up as reports reveal a disaster happening externally, and gets worse as the superior shows signs of exposure, and the government agents endeavor to depart, forcing Matthew Macfadyen’s character to decide between shooting them or permitting their exit and endangering the sterile MI5 environment. This being Spooks, it is unsurprising which one he chooses.

Threads (1984)

The production was inexpensive but one of the most frightening programmes I have viewed due to its harsh realism and bleak government data. Viewed it recently after seeing the first airing; I often attended the bar in Sheffield from the programme which underscored the actuality and the offhand factual official statements that were transmitted. Continuing to be utterly horrifying after three and a half decades.

Severance – The We We Are (2022)

The first season finale of Severance has to be right up there in terms of gripping installments. I spent the entire episode literally perched nervously, straining every sinew with Dylan to keep his hands on the levers that kept the Innies on overtime, while yelling at the Innies to reveal their realities. The final climactic moment – “she is living!” – felt like an explosion.

The 2024 Industry episode White Mischief

The fifth episode of Industry’s third season had my heart racing. I had to pause and get up and exit the space repeatedly because of the sheer scale of the wanton self-destruction I saw. Rishi Ramdani is in major difficulty in his job and domestic life – buried in financial obligations to illegal creditors due to his addictive betting, taking such risks with a gamble on the pound which may result in huge losses for his employer. So of course, he goes on a gambling spree, consumes excessive substances and alcohol and alternates between success and failure, gets beaten to a pulp. Each instance you believe the situation cannot deteriorate further, it deteriorates. Redemption seems possible at the end of the episode but he misses the opening, with horrifying consequences during the season’s final episode. Definitely needed a lie-down after that!

The 2007 Peep Show episode Holiday

Peep Show is not inherently a tense series. But the episode Holiday features such degrees of awkwardness that it’ll have you standing up the whole episode, filled with nervousness. It all ramps up when Jeremy and Mark realize needing to deceive regarding the dog they accidentally run over and later efforts to get rid of it. You then spend the rest of the episode wondering if it might be more awful than cremation, and it can be!

The 2001 The West Wing episode The Two Cathedrals

Nothing I have seen has been as tense compared to my initial viewing the second season finale of The West Wing. 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 with a crisis in Haiti, and the fallout from the non-disclosure of the president’s MS diagnosis, along with affirmation of his plan to run for another term. Excellent TV. Unequaled.

Bodyguard – episode one from 2018

The opening of the British series Bodyguard, with the hero aboard a train accompanied by his small son, ranks among the most gripping episodes I’ve seen. He notices a Muslim female entering the restroom and realizes something is amiss. The bomb diffuser experts are called, enter the train, and attempt to convince the woman to discard her bomb jacket. Tension escalates to a nearly intolerable level, until yes, the vest is diffused.

The 2001 Buffy episode The Body

Buffy enters her house to discover her mother has died due to natural factors, which is the rarest form of demise in this mystical program. The installment lacks any soundtrack, a sullen tone, and we see the episode through the experience of Buffy’s dismay upon uncovering her mother.

The Sopranos – Made in America (2007)

The ultimate sequence of the series finale of the series was extremely nerve-wracking. And if you watched it when it originally aired, you – at the start – didn’t understand the cause. Tony’s enemies, real and imagined, were all vanquished. Doesn’t this resemble the season one conclusion? “Recall the minor details.” However, the vibe is oddly threatening. Almost Twin Peaks levels of terror. The family sit in a restaurant. Meadow finds a parking spot. Tony sadly tells Carmela there’s trouble afoot with an additional associate collaborating with the authorities. Meadow parks the vehicle. Odd persons arrive at the eatery. Look at Tony(?) Meadow parks. Tony puts a record on the jukebox. Meadow parks. The bell sounds, an individual enters. Can’t be Meadow, she’s still parking. Tony raises his gaze. Keep going. It halts. My heart sank roughly 20 minutes after.

The Walking Dead – The Last Day on Earth from 2016

I remained awake to view this installment during the night. It was incredibly tense after the establishment of antagonist Negan discovering the characters, mercilessly mocking his targets and then keeping the death a mystery (ended on a cliffhanger). The victim’s POV shot and the subdued noises – ugh! {We then had to wait for season seven|We then needed to await season
