What Is Pushing Daisies About?
Pushing Daisies is a whimsical, visually striking show created by Bryan Fuller. It follows Ned (played by Lee Pace), a pie-maker with the extraordinary ability to bring the dead back to life with a touch—though if he doesn't touch them again within a minute, they stay alive, but someone else must die in their place. He uses his gift to solve mysteries by resurrecting murder victims and getting answers from them before they are "re-killed" to maintain the balance of life and death.
The series blends mystery, romance, and dark comedy in a world where life and death are intertwined in unique, often playful ways. The show’s quirky aesthetic, colorful visuals, and heartfelt moments make it a cult favorite.
Why Signed, Sealed, Delivered Fans Will Enjoy Pushing Daisies
Clever, Heartfelt Mysteries: Just like the POstables’ passion for solving mysteries and delivering closure, Pushing Daisies features Ned and his partner Chuck (along with their detective friend Emerson) solving mysteries of a more unconventional nature.

Fans of Signed, Sealed, Delivered who enjoy the charm of Norman, Rita, Oliver, and Shane will appreciate the warmth and uniqueness of the Pushing Daisies characters.
A Touch of Whimsy and Magic: While Signed, Sealed, Delivered is grounded in the real world with its focus on emotional closure through letters, Pushing Daisies adds a magical twist, with Ned’s resurrection ability creating a world that feels both fantastical and endearing. This combination of whimsy, magic, and heartfelt storytelling will appeal to fans who love a little bit of the unexpected in their mysteries, while still enjoying the deep emotional payoffs that Signed, Sealed, Delivered delivers.
Themes of Life, Death, and Second Chances: Pushing Daisies uniquely explores life and death, with its central premise revolving around the act of bringing people back to life. This theme of second chances, as well as the exploration of life's fleeting nature, will resonate with Signed, Sealed, Delivered fans, who often see characters finding second chances through the power of a letter or a lost message. Both shows highlight the beauty of redemption and closure, albeit in different (yet equally touching) ways.

What Is NCIS About?
NCIS (Naval Criminal Investigative Service) is a procedural drama that follows a team of special agents as they investigate crimes involving the U.S. Navy and Marine Corps. Led by Leroy Jethro Gibbs (played by Mark Harmon), the team includes experts in various fields—such as forensics, cyber operations, and behavior analysis—working together to solve complex cases involving national security, murder, and espionage.

Why Signed, Sealed, Delivered Fans Will Enjoy NCIS
Teamwork and Strong Bonds: One of the most significant draws for fans of Signed, Sealed, Delivered is the tight-knit team dynamic.

A Strong Sense of Justice: At its core, both shows are about delivering justice. In Signed, Sealed, Delivered, the POstables work to reunite people with undelivered letters, which often leads to emotional resolution and healing. In NCIS, the agents investigate serious crimes and seek to bring perpetrators to justice, but it’s not just about catching the bad guy—it’s about ensuring justice for the victims and their families. Both shows share a commitment to doing what’s right, even when the road to justice is difficult.
Personal Growth and Development: While NCIS has a more action-packed tone, much like the POstables, the characters grow over time. Gibbs and his team face personal challenges, relationships, and emotional losses, and their development is a key part of the show’s success. Fans of Signed, Sealed, Delivered will enjoy seeing how these agents evolve, both professionally and personally, and how their work allows them to heal and grow as individuals.
Cases with Emotional Stakes: While NCIS often involves high-intensity crimes, many episodes have a significant emotional component. The team frequently deals with cases that involve loss, grief, and justice for the victims.

Over the course of 15+ movies, Jennifer becomes an amateur sleuth who works closely with the police while balancing her business, family life, and friendships.
Why Signed, Sealed, Delivered Fans Will Love Garage Sale Mysteries
Everyday Hero with a Heart for Truth: Just like the POstables use undelivered letters to bring closure to people’s lives, Jennifer Shannon uses seemingly ordinary objects to uncover extraordinary truths. Neither character sets out to become a detective—but both follow their hearts and instincts when they sense something is unresolved.
Meaning in the Details: In Signed, Sealed, Delivered, the smallest clue in a letter can lead to life-changing discoveries. Likewise, Jennifer’s success comes from her attention to tiny details—an inscription, a vintage trinket, a misplaced item—that help unravel much bigger mysteries.
Grounded Relationships and Community: Both series feature characters who live full lives outside the mystery itself. Jennifer has a loving (and often worried) husband and a teenage daughter, while the POstables have their deep friendships and evolving romances. These relationships are part of what makes the storytelling so warm and relatable.
Cozy Setting with a Hint of Nostalgia: Much like the comforting world of the Dead Letter Office, Garage Sale Mysteries is filled with old objects, vintage finds, and a love for the past that can be found in Jennifer’s shop Rags to Riches. It taps into the charm of nostalgia—whether it's through a letter from decades ago or a forgotten antique with a secret history.

What Is Murder, She Wrote?
Murder, She Wrote follows Jessica Fletcher (played by Angela Lansbury), a widowed mystery writer and retired English teacher living in the idyllic town of Cabot Cove, Maine.

Clever Mysteries Rooted in Empathy: Like the POstables, Jessica Fletcher approaches each case with compassion and curiosity.

A Love for Community and Connection: Whether it's the small town of Cabot Cove or the close-knit world of the POstables, both series celebrate relationships, community ties, and the beauty of helping others. Jessica forms real bonds wherever she goes—just like Shane, Rita, Norman, and Oliver.
Timeless, Cozy, and Rewatchable: Both shows are perfect for viewers who want something thoughtful, uplifting, and gentle—shows where justice is served, but not at the expense of heart. Murder, She Wrote may have murder at its core, but it never feels dark or disturbing, making it ideal for cozy mystery fans.
Perfect for Viewers Who Love...
Character-driven mysteries
Thoughtful storytelling with emotional payoff
A sense of purpose and deeper meaning in each case

Teamwork and Found Family: If you adored the close-knit, chosen-family dynamic of Oliver, Shane, Rita, and Norman, you’ll find that same energy in The Librarians. The characters grow to trust each other, balance one another’s strengths and weaknesses, and form deep emotional bonds that carry the series forward.
Destiny, Purpose, and a Touch of the Divine: While Signed, Sealed, Delivered often hints at divine intervention guiding the POstables, The Librarians explores fate and purpose in a magical, mythological way. The idea that people are “called” to do great things—through courage, compassion, and intelligence—resonates strongly in both shows.
Adventures That Reveal Truths: Every episode is an adventure—not just physically, but emotionally. The Librarians' journey through magical puzzles and historical mysteries mirrors how the POstables follow the trail of a letter to uncover untold stories and change lives.
