Brace yourself for a tumultuous burst of high-octane action, horror, and heart-warming bromance, thanks to "28 Years Later: The Bone Temple". Up there on the big screen, you'll see Dr. Ian Kelson, Ralph Fiennes’ character, go all in with a performance that screams "commitment." This survival medic uses a human bone-built monument as a stage for a thrill-packed, unforgettable performance, set to Iron Maiden's "The Number of the Beast."

"28 Years Later: The Bone Temple" prides itself in being a dystopian horror flick that's not afraid to juxtapose an Iron Maiden anthem with Duran Duran’s synth-pop. And yes, there's a touch of Radiohead too. The soundscapes are eclectic - delightfully spun on a hand-cranked generator-fueled turntable. Yes, you could say Kelson was ready for an apocalypse of viral-infected cannibals with the spirited preparation levels of a guest on Desert Island Discs.

Director Nia DaCosta and scriptwriter Alex Garland create an exciting world that is an extension of the dystopian future seen in the first three films. Although this sequel might not follow the traditional zombie-script, it expands the boundaries into something more akin to folk horror.

Fiennes truly shines in this film. The isolation and rough-conditions take a toll on his physique, but his eloquent manner and posh education remain unharmed. Towards the end of the film, "28 Years Later: The Bone Temple" successfully pits rationalistic science against barbaric religious fanaticism, creating a gripping climax.

The plot weaves the tender and comedic tale of Dr. Kelson’s relationship with Samson, the alpha specimen of the infected beings. Chi Lewis-Parry's captivating performance as the hulky brute, Samson, adds depth to the narrative. With Kelson’s aid, Samson evolves from a jittery beast to a creature capable of communication.

Meanwhile, a menacing cult led by Sir Lord Jimmy Crystal, played by Jack O’Connell, has started their brutal game of eliminating the infected. Spike, the young protagonist saved by Jimmy Crystal in the previous film, struggles to stomach the cult’s unforgiving nature, and an eventual betrayal seems inevitable.

The narrative effectively captures the struggle between the radical, hopeful sect led by Dr. Kelson and the ruthlessly savage cult headed by Sir Lord Jimmy Crystal. The climactic meeting of these two disparate groups sets up an intriguing arc for the next installment in this series.

Despite some narrative inconsistency, "The Bone Temple" remains an engaging addition to the "28 Years Later" series. Fiennes steals the show with his unforgettable portrayal of Dr. Kelson as a visionary with an edge of lunacy. Combined with stark English settings and a bone-chilling soundtrack, the film will surely satiate the appetites of horror fans.

Ralph Fiennes tethering metal mode and a phenomenal lip-sync performance to Iron Maiden's song "Six six six, the Number of the Beast" is a sight to behold. When the Satanic cult recognizes their mistake in assuming Dr. Kelson to be Satan, with his response, “Nothing is. No one is. There’s just us,” you witness one of the bleakest moments in the series.
