These Sacred Vows Reviews: Is It Worth Watching? Cast & More

There’s something about a wedding in the sun that practically begs for a body in the pool. RTÉ’s new mystery series These Sacred Vows leans into that trope—starring Tom Vaughan-Lawlor as a priest whose murder unravels a weekend of secrets.

Genre: Mystery / Comedy-Drama ·
Network: RTÉ One ·
Starring: Tom Vaughan-Lawlor ·
Year: 2026 ·
Filming Locations: Ireland, Tenerife

Six key specs, one pattern: the show leans hard on its production pedigree and exotic location to offset an uneven critical scorecard.

Are These Sacred Vows any good?

Critics’ consensus

The critical reception to These Sacred Vows lands somewhere between “appealing romp” and “illogical mess.” Ed Power of the Irish Times (established Irish editorial outlet) called it “unoriginal and illogical,” dubbing it “The White Lotus with a green tinge.” On the other side, Joe.ie (Irish lifestyle and entertainment site) praised Vaughan-Lawlor’s performance, describing his priest as “utterly sympathetic” despite the character’s flaws. The series scored a more generous nod from TheJournal.ie (Irish news website), which noted “sexy, funny, subversive” elements woven into the mystery.

Audience reactions on Reddit

Over on r/ireland (Irish community forum), the user consensus is rough. One top comment called it “absolutely appalling,” with the only positive note reserved for Vaughan-Lawlor. Another thread described the show as “a car crash you can’t look away from.” The gap between professional and viewer opinion is narrower than the White Lotus comparisons suggest.

Comparison to The White Lotus

Every review drags in The White Lotus as a reference point—not always to These Sacred Vows‘ advantage. Where Mike White’s HBO series uses its resort setting to methodically peel back character layers, the RTÉ version reportedly rushes its revelations. The show’s flashback structure (each episode revisits the wedding weekend from a different character’s perspective) aims for that same slow-burn effect, but critics argue it lacks the sharp social commentary that made Lotus an event.

The pattern: ambitious framing, uneven execution.

How many episodes are there of These Sacred Vows?

Episode count and runtime

The series consists of six episodes, each structured as a flashback from a different character’s viewpoint (Evoke, Irish entertainment outlet). Exact per-episode runtimes haven’t been published, but standard RTÉ drama slots suggest 50–60 minutes each.

Broadcast schedule on RTÉ One

RTÉ scheduled the premiere for Sunday 1 February 2026 at 9:30pm on RTÉ One and RTÉ Player (Joe.ie, entertainment site). The first two episodes were made available simultaneously on RTÉ Player the same evening, a strategy increasingly common for Irish public-service streaming.

Why it matters: a six-episode order gives the show a tight window to prove itself—short enough to binge, long enough to build a mystery.

Where was These Sacred Vows filmed?

Filming locations in Ireland

Key Irish scenes were shot at Ballyadams Castle, County Laois (Evoke, Irish entertainment outlet). The same location has hosted productions involving Brad Pitt’s production company, giving the castle a track record for high-profile shoots. Exterior and interior scenes at the castle likely stand in for the wedding venue’s earlier sequences in Ireland before the action moves abroad.

Tenerife as the wedding setting

The bulk of the murder-mystery drama unfolds on the Spanish island of Tenerife. The show uses the island’s sunshine and resort architecture as a visual contrast to the emotional claustrophobia of the family wedding—a trick familiar from The White Lotus‘s Hawaii and Sicily seasons. The choice of Tenerife gives the series a distinct Canary Islands flavour rather than the Mediterranean gloss of other recent crime dramas.

The trade-off: stunning backdrop, but critics argue the location does more work than the script.

What happens in These Sacred Vows?

Plot summary

An Irish wedding in Tenerife turns into a murder mystery when the priest—played by Tom Vaughan-Lawlor—is found dead in a swimming pool. The story then unfolds backwards and sideways: each of the six episodes rewinds to the same wedding weekend, telling events from a different character’s memory. The opening episode shows Fr. Vincent arriving in Tenerife and discovering he must share accommodation with a rowdy group of hedonistic young people (Joe.ie, entertainment site).

Main characters and their secrets

Beyond the priest, the ensemble includes the bride’s mother Sandra (Justine Mitchell) and father Jerry (Jason O’Mara), plus wedding-party guest Ava (India Mullen). Each character carries a secret that the murder forces to the surface. Vaughan-Lawlor has described the series as “a romp through the Irish in the sun” (via TheJournal.ie, Irish news site). The show tackles themes of Irish identity and the country’s evolving relationship with the Catholic Church.

The catch: a promising premise buried under a structure that some viewers find confusing rather than clever.

Who is in the cast of These Sacred Vows?

Lead cast members

Tom Vaughan-Lawlor leads as Fr. Vincent, the murdered priest at the centre of the mystery. Known for his roles in Peaky Blinders and Dublin Murders, Vaughan-Lawlor has been the lone point of consensus across reviews—even the harshest critics single out his performance. Adam John Richardson also appears as a main character, alongside Tom Hanson, Aoife Hinds, Shane Daniel Byrne, and Catherine Bohart (Evoke).

Supporting roles

Justine Mitchell takes the role of Sandra, the mother of the bride; Jason O’Mara plays Jerry, the father; and India Mullen plays Ava, a guest at the wedding party. The show also confirms a sprawling ensemble—the Irish Times review noted the “sprawling cast” as both a strength and a weakness, since multiple characters compete for screen time in only six episodes.

Behind the scenes, the production involves RTÉ’s Head of Drama David Crean, Dermot Horan of Acquisitions, Treasure Entertainment’s Rob Walpole and Rebecca O’Flanagan, and Banijay Rights’ Cathy Payne and Simon Cox, plus Fís Éireann/Screen Ireland’s Kate McColgan.

The implication: a strong cast in search of a tighter script—the talent is there, the material hasn’t convinced everyone.

What the critics and cast are saying

“Unoriginal and illogical… The White Lotus with a green tinge.”

— Ed Power, Irish Times (Irish Times review)

“Sexy, funny, subversive… a romp through the Irish in the sun.”

— Tom Vaughan-Lawlor, via TheJournal.ie (TheJournal.ie interview)

“Absolutely appalling show. The only positive comment is for Tom Vaughan-Lawlor.”

— Reddit user, r/ireland (Reddit discussion thread)

The divergence between these perspectives tells the story: a lead performance that commands attention, wrapped in a package that leaves many viewers cold.

For RTÉ, the gamble on a prestige murder mystery has generated conversation—but the mixed critical reception means the decision to renew for a second season hinges on viewership numbers. For Irish audiences deciding whether to invest six hours, the choice is clear: if you’re a Vaughan-Lawlor completist or a patient fan of uneven ensemble mysteries, give it a shot; if you need tight plotting and logical resolution, the critical consensus suggests skipping it.
