‘I definitely needed a lie-down after that!’ Your most gripping episodes of TV ever

Spooks – I Spy Apocalypse from 2003

The episode begins with the intelligence unit locked down as part of a simulation concerning a fictional terrorist event, monitored by two government representatives. As things progress, it appears that there really has been an attack and a chemical weapon has been unleashed. The tension ratchets up as messages indicate a crisis unfolding beyond their walls, and escalates as the boss appears to be infected, and the two Home Office officials attempt to leave, compelling the character played by Matthew Macfadyen to choose between firing at them or allowing them to leave and potentially infecting the secure MI5 headquarters. This being Spooks, the outcome is expected.

Threads (1984)

Threads had minimal funding yet among the scariest shows I’ve ever seen because of the stark reality and bleak government data. Saw it not long ago after seeing the first airing; I used to visit the pub in Sheffield from the programme that highlighted the truth and the offhand factual official statements that were transmitted. Remaining completely frightening after three and a half decades.

Severance – The We We Are (2022)

The concluding episode of Severance’s debut season deserves a top spot among intense episodes. 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 reveal their realities. The final climactic moment – “she’s alive!” – resembled a outburst.

Industry – White Mischief (2024)

The fifth episode of Industry’s third season caused my heart to pound. I needed to stop and stand and exit the space repeatedly owing to the vast degree of the wanton self-destruction I was witnessing. Rishi Ramdani is in major difficulty professionally and personally – buried in financial obligations to illegal creditors because of his compulsive gambling, assuming hazardous chances with a gamble on the pound which may result in huge losses for his employer. Naturally, he embarks on a betting frenzy, uses copious drugs and alcohol and experiences wins and losses, is severely assaulted. Each instance you believe it can’t get any worse, it does. There’s hope of redemption by the episode’s conclusion but he misses the opening, with horrifying consequences during the season’s final episode. Certainly required a rest afterward!

Peep Show – Holiday from 2007

The series Peep Show isn’t typically anxiety-inducing. However, the Holiday episode includes such amounts of embarrassment that it will make you rise throughout the entire episode, permeated with worry. It all ramps up as Jeremy and Mark discover needing to deceive regarding the dog they accidentally run over and following tries to eliminate it. You then occupy the remainder of the episode doubting if it can actually be more terrible than burning, 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 second season finale of The West Wing. The episode starts with the aftermath of the demise (in a car crash) of the president’s personal secretary and builds to a peak with a crisis in Haiti, and the fallout from the non-disclosure of the president’s MS diagnosis, with confirmation of his intention to run for another term. Wonderful television. Unsurpassed.

The 2018 Bodyguard premiere episode

The beginning of the UK show Bodyguard, with the protagonist on a train alongside his juvenile boy, is personally a top tense installment. He observes a woman in Islamic attire 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 a practically unendurable point, until yes, the vest is diffused.

Buffy the Vampire Slayer – The Body (2001)

Buffy arrives at her residence to find her mum has passed away due to natural factors, which is the most unusual type of death in this paranormal series. The show features no musical score, a gloomy atmosphere, and we witness the episode via the perspective of Buffy’s dismay upon uncovering her mother.

The Sopranos – Made in America from 2007

The final scene of the final episode of the show was pants-wettingly tense. And if you watched it when it originally aired, you – at first – weren’t sure why. Tony’s enemies, real and imagined, were all overcome. Surely this has the feel of the season one ending? “Recall the minor details.” However, the vibe is oddly threatening. Approaching Twin Peaks-esque horror. The family sit in a restaurant. Meadow parks. Tony gloomily informs Carmela problems are brewing with yet another of his crew collaborating with the authorities. Meadow parks the vehicle. Odd persons arrive at the eatery. Stare at Tony(?) Meadow is parking. Tony plays a track on the music machine. Meadow finds a spot. The bell sounds, an individual enters. Can’t be Meadow, she’s still parking. Tony looks up. Keep going. It ceases. My heart dropped from my mouth 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 so intense following the introduction of villain Negan discovering the characters, mercilessly mocking his targets and then keeping the death a mystery (ended on a cliffhanger). The point-of-view shot from the victim and the subdued noises – oh no! {We then had to wait for season seven|We then needed to await season
