‘I absolutely had to rest after that!’ The most nerve-wracking television episodes you’ve seen

Spooks – I Spy Apocalypse (2003)

The episode begins with the MI5 agents restricted while undergoing a drill about a potential terror incident, monitored by two government representatives. As the situation develops, it becomes clear a real incident has taken place and a chemical agent deployed. The suspense builds as reports reveal a catastrophe taking place outside, and escalates as the superior shows signs of exposure, and the government agents endeavor to depart, compelling the character played by Matthew Macfadyen to opt for either shooting them or allowing them to leave and endangering the sterile MI5 environment. This being Spooks, the outcome is expected.

The 1984 production Threads

Threads had minimal funding yet among the scariest shows I have ever watched because of the stark reality and grim official statistics. Saw it not long ago after seeing the first airing; I frequently went to the Sheffield pub shown in the series which underscored the actuality and the glib matter-of-fact official information which was broadcast. Still absolutely terrifying decades on.

The 2022 Severance episode The We We Are

The first season finale of Severance has to be right up there among intense episodes. I was throughout the episode literally perched nervously, exerting with Dylan to keep his hands on the levers that sustained the Innies’ extended time, while shouting to the Innies to get their truths out there. The concluding高潮 – “she’s alive!” – felt like an explosion.

Industry – White Mischief (2024)

The fifth episode of Industry’s third season made my pulse quicken. I was compelled to halt and rise and leave the room several times owing to the vast degree of the reckless self-harm I was witnessing. Rishi Ramdani is in deep shit professionally and personally – buried in financial obligations to loan sharks owing to his uncontrollable gaming, engaging in dangerous ventures on a wager involving sterling that might cost his firm millions. Naturally, he embarks on a betting frenzy, does tons of drugs and drink and wins, loses, wins, is brutally attacked. Every time you think the situation cannot deteriorate further, it deteriorates. There is a chance for salvation at the end of the episode but he misses the opening, leading to terrible outcomes during the season’s final episode. Definitely needed a lie-down after that!

Peep Show – Holiday from 2007

Peep Show is not inherently a tense series. But the episode Holiday features such degrees of awkwardness that it can cause you to stand the whole episode, filled with nervousness. The situation intensifies once Jeremy and Mark find themselves needing to deceive regarding the dog they unintentionally hit and later efforts to get rid of it. You subsequently use the rest of the installment questioning whether it truly can be worse than incineration, and it turns out to be!

The West Wing – The Two Cathedrals from 2001

Nothing I’ve watched has been more intense as when I first saw the season two finale to The West Wing. The installment begins with the consequences of the passing (in a road incident) of the president’s private assistant and builds to a peak with a crisis in Haiti, and the effects of the withheld information about the president’s MS condition, along with affirmation of his plan to run for another term. Superb programming. Unsurpassed.

Bodyguard – episode one from 2018

The opening of the British series Bodyguard, with the hero aboard a train with his young son, ranks among the most gripping episodes I’ve seen. He spots a Muslim woman entering the restroom and knows something is off. The bomb squad is alerted, get on the train, and try to persuade the woman to discard her bomb jacket. Anxiety builds to an almost unbearable degree, until, finally, the vest is neutralized.

Buffy the Vampire Slayer – The Body from 2001

Buffy arrives at her residence to find her mum has passed away of natural causes, which is the least common kind of passing in this supernatural show. The episode has no background music, a somber mood, and we see the episode through the experience of Buffy’s dismay upon uncovering her mother.

The Sopranos – Made in America (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 the start – didn’t understand the cause. Tony’s foes, genuine and fictional, were all vanquished. Surely this has the feel of the season one ending? “Recall the minor details.” Yet the atmosphere is strangely foreboding. Nearly Twin Peaks-like fear. The clan sits in an eatery. Meadow finds a parking spot. Tony sorrowfully notifies Carmela problems are brewing with an additional associate cooperating with the officials. Meadow secures a parking space. Strange people enter the restaurant. Look at Tony(?) Meadow continues to park. Tony selects a song on the jukebox. Meadow parks. The bell sounds, an individual enters. It cannot be Meadow, she is still parking. Tony glances upward. Keep going. It stops. My heart sank roughly 20 minutes after.

The 2016 The Walking Dead episode The Last Day on Earth

I stayed up to watch this episode at 2am. It was so intense after the buildup of bad guy Negan finding the group, mercilessly mocking his targets and then leaving the victim unknown (ended on a cliffhanger). The first-person perspective of the victim and the subdued noises – ugh! {We then had to wait for season seven|We then needed to await season
