Crazy Ex-Girlfriend is an American romantic musical comedy-drama television series that premiered on October 12, 2015, on The CW and ran for four seasons, ending on April 5, 2019.

The show received widespread critical acclaim and developed a cult following, despite drawing consistently low ratings throughout its four-season run.

She receives a diagnosis of borderline personality disorder and begins attempting to take better care of her mental health and take responsibility for her actions.

After she begins an on-again-off-again relationship with Nathaniel, a series of events leads to Rebecca pushing her stalker Trent off a roof.

With all the main cast members becoming more mature and emotionally healthy, Rebecca feels pressured to choose between romance with Josh, Nathaniel, and Greg.

[17] The series has been extensively reworked for The CW, expanding the show format from a half-hour to a full hour and adjusting the content for broadcast television, as the original pilot was produced for premium cable.

[23] On September 30, 2014, Santino Fontana, Donna Lynne Champlin, Vincent Rodriguez III and Michael McDonald joined Rachel Bloom in the series regular cast.

[28] In 2017, David Hull and Scott Michael Foster, who portray White Josh and Nathaniel respectively, were promoted to series regulars for season three.

[30] "Crazy Ex-Girlfriend: Original Television Soundtrack (Season 1 – Volume 1)" was released on February 19, 2016, in both explicit and clean versions.

It includes all the songs from the last 10 episodes of season one, as well as demos of "JAP Battle", "I Could If I Wanted To", "Women Gotta Stick Together", "Group Hang", and "You Stupid Bitch".

The full album was released July 20, 2018 and includes a demo of "The End of the Movie" by Adam Schlesinger as well as a cut song, "Settle For Her (Reprise)" by Scott Michael Foster.

Arguably the most important recurring theme of Crazy Ex-Girlfriend is the show's portrayal of mental illness and treatment.

[66][67][68][69][70] Another defining feature of Crazy Ex-Girlfriend is its frank portrayal of female sexuality and the reproductive system, both of which serve as sources of the show's cringe humor.

In the episode "To Josh, with Love", characters have frank and honest discussions regarding female sexuality and clitoral stimulation.

The show's open and frank approach to women's health topics is evidenced best by when Paula had an abortion in the second season and her friends and family focused on the emotional impact of her decision, rather than questioning or shaming it.

[92][93] This resulted in Heather developing a lazy, aimless, unenthusiastic and somewhat apathetic personality, demonstrating the complexity of parenting.

[95] Review aggregation website Rotten Tomatoes gave the first season a 97% positive rating, with an average rating of 7.67 out of 10 based on reviews from 58 critics, with the site's consensus stating: "Lively musical numbers and a refreshing, energetic lead, Rachel Bloom, make Crazy Ex-Girlfriend a charming, eccentric commentary on human relationships.

The site's critical consensus reads, "Crazy Ex-Girlfriend remains delightfully weird, engaging, and even more courageous and confident in its sophomore outing.

[102] The critical acclaim that the show enjoyed was a factor in its renewal through four seasons, in spite of consistently low Nielsen ratings.
