Generated Title: Lili Reinhart's "Hal & Harper": Is Sibling Codependency a Trend, or Just Good TV?
The entertainment industry loves a trend. From vampires to zombies, Hollywood cycles through obsessions like a toddler with a new toy. So, when Lili Reinhart—best known for Riverdale—stars in Hal & Harper, a Mubi limited series about sibling codependency, it begs the question: is this a fleeting fad, or is there something deeper at play?
The show, created by and co-starring Cooper Raiff, centers on siblings Hal and Harper as they navigate the choppy waters of young adulthood. Their bond is tested when their father (Mark Ruffalo) announces he's expecting another child. The show explores the impact of childhood wounds and the complex ways sibling relationships shape adult identities. The series finale airs November 30th, so it’s too early to gauge its long-term viewership. (Early numbers are decent, though Mubi doesn’t release precise figures.)
Sibling Stories: A Growing Genre?
While Hal & Harper might seem unique, a closer look reveals a pattern. Sibling relationships have been increasingly explored in recent years. Shows like Succession (the Roy siblings), Fleabag (Fleabag and her sister Claire), and even going back to Arrested Development (the Bluths) all hinge on the intricate dynamics between siblings. The question is, why now?
One could argue it's a reflection of societal shifts. With traditional family structures evolving and social support systems fraying, siblings often become each other's primary confidants and support network. They become the constant in a world of variables. Is this a quantifiable trend? Hard to say without sociological data. But the sheer volume of sibling-centric narratives suggests a cultural resonance. I've seen similar patterns in other sectors; the rise of "co-living" spaces, for example. People are craving connection.
Reinhart herself acknowledges the show's relatability. In an interview, she discussed the painful reality of relationships ending, even after years of shared history. "To uncouple from six years with someone that you’ve moved into a house with and truly imagined you would get married to [is] heartbreaking," she said. But is the heartbreak of a romantic relationship really analogous to the fracturing of a sibling bond? The show seems to suggest so, presenting the sibling relationship as a primary, almost marital, bond.

Data Points: Reinhart's Career Trajectory
Looking beyond the narrative itself, Reinhart's involvement adds another layer of intrigue. Post-Riverdale, she's strategically chosen roles that showcase her range. From the dark comedy Hustlers to Chemical Hearts, she’s actively diversifying her portfolio. Hal & Harper seems to fit this pattern, offering her a chance to delve into more nuanced, character-driven material. Is this a smart career move? Probably. Riverdale was a teen drama; this is decidedly more adult.
But how does Hal & Harper stack up against her other projects in terms of critical reception and audience engagement? Data is scarce. Mubi's streaming numbers are opaque, and critical reviews are mixed. It's tough to definitively say if this is a hit.
And this is the part of the analysis that I find genuinely puzzling. The show premiered at Sundance back in January. It's been available on Mubi for weeks. Yet, the media buzz is relatively muted. Is it a marketing issue? Is the show simply not connecting with a wider audience? Or is it a deliberate strategy to target a niche demographic? Details on Mubi’s marketing spend remain elusive, but the relatively small footprint is telling.
Consider, too, Reinhart's public image. She's known for her openness about mental health and her willingness to challenge conventional beauty standards. Her fashion choices—like the lime-green pumps she recently sported while promoting the show—often make headlines. (The pumps, incidentally, are from Tory Burch’s Resort 2026 collection.) This suggests a carefully curated brand. Hal & Harper aligns with this brand, exploring complex emotional terrain and offering a realistic portrayal of young adulthood.

Just Another Millennial Angst-Fest?
Ultimately, Hal & Harper's success will hinge on its ability to resonate with viewers. While the sibling codependency theme might be trendy, the show's exploration of heartbreak, identity, and family dynamics is undeniably timeless. Whether it's a flash in the pan or a sign of things to come remains to be seen.
