The Sentimental Garbage podcast is an exciting blend of literature and pop culture. Earlier episodes of the podcast explored intelligent critiques of popular books. As the show tells audiences, most of the books they examine on the show have a "chick-lit" theme. Episodes explore characters, settings, and moods captured by authors from various eras.

As the Sentimental Garbage podcast progressed and gained popularity, the topics broadened. Instead of just books, now the show discusses TV shows, movies, music, and culture. Listeners hear conversations about books such as the angsty High Fidelity and I Don't Want To Come. There are discussions about movies like Bridget Jones' Diary, Juno, and The Bodyguard. The Thorn Birds, Sex and the City, and Gilmore Girls are some TV shows on the podcast.

Caroline O'Donoghue, host of the show, is an award-winning Irish writer. Her first book, All Our Hidden Gifts, made the New York Times bestseller list. She also wrote The Rachel Incident and Promising Young Women. Caroline has written for Harper's Bazaar, The Times of London, and Grazia. She started the Sentimental Garbage podcast in 2018. Caroline and her guests hold conversations mingled with humor, wit, and insight. They discuss books, movies, and TV shows against the backdrop of contemporary society.

Sentimental Garbage's appeal rests on its candid chats about society. It presents the world through the eyes of sometimes complex literary characters. Caroline and her guests share their perspectives with beautiful resonance. Reality TV is the topic of conversation with writer Pandora Sykes. Filmmaker Emma Forrest talks about Cher in another episode. Kate Young has appeared on the show several times. She discusses Julia Roberts' Mona Lisa Smile in one episode. In another episode, they discuss why people love baking.

Other guests include Jen Cownie and Hanna Flint. The show addresses topics with sincerity and unusual depth. Whether they talk about fan fiction, Taylor Swift, or millennial women, they do so with insight and wit. New episodes of Sentimental Garbage premiere on a periodic basis.
