out of four stars. Critics have also noted Green's evolution as an author. With the release of the Turtles All the Way Down in 2017, several reviewers referenced a dismissive perception of Green's now very popular œuvre as "sad teen books", which had emerged since the success of The Fault in Our Stars. Despite this, they praised Turtles All the Way Down as truthful and authentic enough to transcend these imagined drawbacks. Matt Haig of The Guardian wrote, "[Turtles All the Way Down] often dwells in cliché, but only as pop songs and epic poems do, mining the universal to create something that speaks to the familiar rhythms of the heart.

Green has readily discussed what he believes to be flaws in his novels when he looked at them in retrospect. Additionally, in response to a fan's tweet, Green apologized for using the word retarded in Paper Towns, stating, "Yeah, I regret it. At the time, I thought an author's responsibility was to reflect language as I
