The Summer I Turned Pretty 3: is it a true story?
The Summer I Turned Pretty is not based on real events. The Prime Video series is based on the eponymous trilogy by Jenny Han, also the author of To All the Boys I’ve Loved Before. The TV adaptation follows the novels closely, depicting Belly’s evolution and the complex love triangle with the Fisher brothers. Jenny Han actively participated in the adaptation as creator and showrunner, ensuring faithfulness to the books and supervising dialogue and character development.
What reviews say about The Summer I Turned Pretty
Overall, critics gave the series positive reviews, though with some reservations. On Rotten Tomatoes, season scores range from 76–83%, with the third season receiving an 83% rating from critics but a lower audience score (around 50–60%).
Critics praise the series for its smart use of the young adult genre. While summer flings, love triangles, and romantic tension are familiar tropes, the show makes them feel authentic with believable characters, natural dialogue, and deeper themes like loss and emotional growth. Some note occasional melodrama or predictable twists, but overall the balance of romance, drama, and nostalgia works well for its audience.
Where was The Summer I Turned Pretty filmed?
Principal photography took place in North Carolina, USA, with coastal locations including Carolina Beach, Fort Fisher, and Padgett Station. The seaside setting is central to the series, both as a physical space and a symbol: a place of memories, beginnings, and loss. The North Carolina beaches help convey the warm, bright yet melancholic atmosphere that the script requires.
