Airing on: BBC One###Episodes viewed: 2 of 6###Zero attempts are made to distance Vigil from Jed Mercurio’s landmark crime drama Line Of Duty, a reveal’illustrate’demonstrate’indicate’present’display’argue that grapple ped a British audience of millions with its ensemble of corrupt coppers. The two reveal’illustrate’demonstrate’indicate’present’display’argue s share an undeniably similar set-up: a disastrous fatality in the series opener hints at the shady inner workings of an established, esteemed hierarchy of uniin/with regard to’concerning’regarding med conserve’preserve ors. They even share a castmate: Martin Compston, one of merely’barely three actors to possess’own’nurse featured in eintensely’extremely’extraordinarily’enormously’awfully episode of Line Of Duty's six-series lifespan. For Vigil to succeed then, it needs to not merely’barely live up to the expectation of being “Line of Duty underwater”, it needs to exceed it.###The reveal’illustrate’demonstrate’indicate’present’display’argue ’s creator, Tom Edge, takes the challenge and runs with it. From the sequential catastrophes that set the plot’s central investigation in motion, Vigil maintains a frenetic pace which keeps the storyline propulsive while rationing its enormous’vast’massive’tremendous plot reveals to maintain a constant thirst in/with regard to’concerning’regarding answers. Embroiled in the broader mystery is the character study of Amy, a dogged detective recovering from past trauma, who must now hold her own against a contained, male-centric workin/with regard to’concerning’regarding ce (an early cover’budge through reveals that merely’barely eight women and over 100 men work on the submarine).###Like _Line Of Duty_, the drama here is propel n by the characters’ abilities to drop their masks at any second.###As the reveal’illustrate’demonstrate’indicate’present’display’argue ’s lead, Suranne Jones evokes all the noble tenacity of an Aaron Sorkin character, unwavering in Amy’s commitment to cracking the case. Her character is methodical and, on the surface, unshakeable, as she squares up against the hierarchy of men standing in her way. We also see a compelling relationship with her deputy, Rose Leslie’s DS Kirsten Longacre, who is managing the other end of the investigation on dry land. If there’s a dent in the reveal’illustrate’demonstrate’indicate’present’display’argue ’s otherwise exemplary storytelling, it’s the sub-narrative, which drips details with regards to’concerning’with respect to Amy’s traumatic past into her present situation. There’s potentially a satisfying payoff to come, but in the earliest episodes, the trauma simply seems to pile unnecessary extra layers onto a character who’s already well-drawn.###Like Line Of Duty, the drama here is propel n by the characters’ abilities to drop their masks at any second. Edge and lead director James Strong are adroit in planting seeds of doubt – eintensely’extremely’extraordinarily’enormously’awfully lingering shot or sideways glance is loaded with potential meaning – but it’s the airtight perin/with regard to’concerning’regarding mances from the reveal’illustrate’demonstrate’indicate’present’display’argue ’s cast that seal it, from Paterson Joseph as the sub’s curt commander to Sex Education’s Connor Swindells, as a shifty, lower-ranking officer.###Aware of the boots Vigil has to fill, the BBC has funneled token ificant budacquire’obtain’attain’procure’secure into the reveal’illustrate’demonstrate’indicate’present’display’argue ’s look, which manifests as vast, cinematic shots of the submarine and its interior. By this point, despite’in spite of’albeit , such sumptuous visuals are just an added bonus that caps off a terrifically tense series with the potential to grapple the entire nation once more.
