‘I definitely needed a lie-down after that!’ Your most nerve-wracking episodes of TV of all time

Spooks – I Spy Apocalypse (2003)

The episode begins with the MI5 agents locked down as part of a simulation concerning a fictional terrorist event, supervised by two Home Office agents. As the situation develops, it becomes clear a real incident has taken place with a chemical weapon released. The suspense builds as incoming communications show a disaster happening externally, and gets worse as the superior shows signs of exposure, with the two officials trying to exit, pushing the protagonist portrayed by Matthew Macfadyen to opt for either shooting them or allowing them to leave and endangering the sterile MI5 environment. As this is Spooks, it is unsurprising which one he chooses.

The 1984 production Threads

The production was inexpensive yet among the scariest shows I have viewed due to its harsh realism and dismal official figures. Viewed it recently following the initial broadcast; I frequently went to the Sheffield pub from the programme which underscored the actuality and the glib matter-of-fact official information that were transmitted. Continuing to be utterly horrifying after three and a half decades.

Severance – The We We Are (2022)

The concluding episode of Severance’s debut season ranks highly in terms of gripping installments. I remained for the whole show quite literally on the edge of my seat, pushing alongside Dylan to maintain his grip on the controls that kept the Innies on overtime, while yelling at the Innies to get their truths out there. The concluding高潮 – “she’s alive!” – was like an eruption.

Industry – White Mischief from 2024

Installment five in Industry’s third series had my heart racing. I had to pause and get up and leave the room several times because of the sheer scale of the deliberate ruin I was witnessing. Rishi Ramdani faces serious trouble in his job and domestic life – up to his eyeballs in debt from unscrupulous lenders due to his addictive betting, assuming hazardous chances with a gamble on the pound which may result in huge losses for his employer. Inevitably, he starts a gaming binge, does tons of drugs and drink and experiences wins and losses, gets beaten to a pulp. Each instance you believe the situation cannot deteriorate further, it does. There is a chance for salvation at the end of the episode but he squanders the opportunity, with horrifying consequences in the concluding part of the season. Absolutely had to relax following 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 can cause you to stand for the full show, permeated with worry. The tension escalates 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 can be!

The West Wing – The Two Cathedrals (2001)

Nothing I’ve watched has been more intense than the first time I watched the concluding episode of The West Wing’s second season. The installment begins with the consequences of the death (in a traffic accident) of the president’s private assistant and reaches a crescendo with a crisis in Haiti, and the effects of the withheld information about the president’s MS condition, with confirmation of his intention to seek re-election. Wonderful television. Unsurpassed.

Bodyguard – episode one (2018)

The start of the British program Bodyguard, with the protagonist on a train alongside his juvenile boy, is for me one of the most intense episodes ever. He observes a woman in Islamic attire heading to the toilet and knows something is off. The bomb squad is alerted, board the train, and endeavor to coax the woman to remove her explosive vest. Tension escalates to an almost unbearable degree, until, finally, the vest is neutralized.

Buffy the Vampire Slayer – The Body (2001)

Buffy comes into her home to realize her mom has deceased of natural causes, which is the most unusual type of death in this paranormal series. The episode has no background music, a gloomy atmosphere, and we see the episode through the experience of Buffy’s astonishment upon finding 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 – initially – were uncertain of the reason. Tony’s foes, genuine and fictional, were all vanquished. This seems similar to the first season’s finale, right? “Remember the little things.” But the mood is bizarrely ominous. Almost Twin Peaks levels of terror. The family gathers in a diner. Meadow parks. Tony sorrowfully notifies Carmela difficulties are arising with another member of his team working with the government. Meadow secures a parking space. Odd persons arrive at the eatery. Gaze at Tony(?) Meadow continues to park. Tony puts a record on the jukebox. Meadow finds a spot. The bell sounds, an individual enters. Can’t be Meadow, she’s still parking. Tony looks up. Don’t stop. It stops. My heart dropped from my mouth about 20 minutes later.

The 2016 The Walking Dead episode The Last Day on Earth

I kept late hours to see this show during the night. It was incredibly tense after the establishment of antagonist Negan locating the survivors, savagely teasing his prey then not knowing who he killed (ended on a cliffhanger). The victim’s POV shot and the muffled sounds – argh! {We then had to wait for season seven|We then needed to await season
