These days, Sam Heughan is a fan-favorite presence on the small screen, but he wouldn't have garnered mainstream awareness if it hadn't been for his breakout role in the hit television adaptation of Diana Gabaldon's Outlander book series. Over the last decade, Heughan's performance as a swoony Scottish hero and self-professed wife guy on the Starz series has propelled him to certified heartthrob status — but with Outlander finally set to conclude with its eighth and final season at a date yet to be determined, it's no wonder Heughan has been taking other projects, perhaps in an effort to step out from the long shadow that Jamie Fraser still casts.

On paper, The Couple Next Door, Starz's six-part psychological thriller based on the Dutch series Nieuwe Buren, has a lot going for it, as messy relationship dynamics play out against the idyllic backdrop of suburbia — and at first, the show gives every indication that it's ramping up to an erotic, twisted climax. But despite best attempts from Heughan, along with his main co-stars Eleanor Tomlinson (Poldark), Jessica de Gouw (Arrow), and Alfred Enoch (How To Get Away With Murder), the series frustratingly pivots away from its most intriguing elements in favor of weaker B-plots, ultimately resulting in a hectic finale that relies too heavily on outdated, regressive tropes to drive its biggest conflicts.

What Is 'The Couple Next Door' About?

Primary school teacher Evie Greenwood (Tomlinson) and her partner, journalist Pete Thomas (Enoch), are looking for a fresh start in more ways than one. Moving to a small suburb in Leeds feels like the right next move for the young couple, especially once they run into their next-door neighbors, PC Danny Whitwell (Heughan) and his wife, yoga instructor Becka (de Gouw), while attempting to lug their belongings into the new house. Evie is drawn to the beautiful young couple from the start for a variety of reasons, the most obvious being her attraction to Danny. However, as someone who grew up in a very conservative, religious household, Evie's eyes are soon opened to her neighbors' more non-traditional lifestyle.

As the four spend more and more time together, Becka and Danny disclose the fact that they're non-monogamous, even if they make a point of always "playing" together with other couples. As Evie starts to entertain the idea of experimentation, Pete's reservations about opening up their relationship lead to rising tensions. Yet their drama isn't the only one that plays out within this seemingly sleepy community. As a somewhat lowly traffic cop with little authority and mounting bills to pay, Danny begins to accept late-night jobs that don't exactly fall on the legal side of things — right around the time that Pete starts digging into local corruption for his latest exposé. As for Becka, she's built a successful social media presence, but she's also attracted a creepy real-life stalker in the process, one who isn't willing to go away without throwing a wrench into her picture-perfect existence.

'The Couple Next Door' Begins as a Better Show Before Pivoting Into a Worse One

Over the first half of its eight episodes (all of which were provided for review), The Couple Next Door has a lot of promise, especially when it focuses on the evolving and tangled relationships between its main foursome. Yet the series is also majorly underserved by its pacing, as it spends a significant amount of time devoted to building up that tension and then ultimately fails at offering a more nuanced depiction of attraction and obsession given the sheer number of other characters and storylines that have to be juggled. The problem is that none of these secondary threads are even remotely as interesting as the main one; every scene spared for Becka's stalker, or Danny's off-the-books job, or any side character for that matter, feels like a missed opportunity to return to the emotional rollercoaster playing out between the two leading couples. Cutting at least one of these B-plots may also have resulted in a better lead-up to the finale, which climaxes in a way that feels extreme, even for these four.

Some characters are afforded better treatment — in many instances, de Gouw's Becka feels like one of the only mature adults in the room — but others seem to regress in increasingly drastic ways purely for the sake of drama. Unfortunately, The Couple Next Door joins recent films like Nightbitch and Babygirl in giving one of its female characters a backstory steeped in extreme, cult-like religion that feels perplexing at best and reductive at worst in justifying sexual exploration. Evie's ignorance about polyamory could've been filtered through a simpler, more straightforward premise of a woman embracing her innermost desires, and the blurred lines that result when she finds herself falling for the one person she shouldn't. But Tomlinson's character is done the biggest disservice over the course of the season; as Evie's fixation on Danny intensifies, she becomes even more of a caricature, with her later scenes devolving into stereotypical '80s erotic thriller territory — and not in a way that can be considered complimentary. The show's men don't fare any better; while he does have excellent chemistry with both Tomlinson and de Gouw in the scenes that call for it, Heughan is given very little to do other than handsomely brood. Meanwhile, Enoch, in welcome contrast, initially gets to play a more level-headed and less alpha presence, but, like Evie, Pete's characterization annoyingly falls prey to jealousy and rage.

In many ways, this show would have been better off solely revolving around these objectively attractive people and the palpable tension that stems from them debating whether they should all sleep together — and to a point, The Couple Next Door delivers on that front. But the season quickly becomes derailed by way of less intriguing subplots, disappointing character regression, and poor pacing that struggles to build to a satisfying finale. It'd be one thing if there was a promise for more at the end of it all, but with the show having already been renewed for a Season 2 featuring a completely new cast, there's no opportunity for this version of The Couple Next Door to continue. Given how it all wraps up, though, maybe that's for the best.

The Couple Next Door premieres January 17 on Starz.
