Cousins Kal-El and Kara Zor-El are sent to Earth before Krypton's impending destruction.

Kara learns that there are hundreds of aliens on Earth, most of whom came from a prison that was run by her mother, Alura. Her actions attract the attention of an alien called Vartox, and she is able to defeat him, although he then kills himself.

Production

Development

By September 2014, Warner Bros. Television was looking to create a television series centered around Kara Zor-El / Supergirl. Executive producers for the series include Greg Berlanti (also a creator/producer for Arrow and The Flash), Ali Adler, who were both writing the script, and Berlanti Productions' Sarah Schechter. DC Comics' Geoff Johns was also expected to be part of the project. Titles under consideration for the series included Super and Girl. Berlanti confirmed the show shortly after, and stated it was in development and had yet to be pitched to networks. On September 20, it was announced that CBS had landed Supergirl with a series commitment, with an expected premiere in 2015 of the 2015–16 television season.

The show was officially picked up to series on May 6, 2015. On November 30, 2015, CBS ordered an additional seven episodes of Supergirl, for a full season of 20 episodes.

Writing

In January 2015, CBS Entertainment chairwoman Nina Tassler revealed the show would be a procedural, saying, "There will be [crime] cases, but what [executive producers] Ali Adler and Greg Berlanti pitched was a real series arc for her. The beauty of it is now with shows like The Good Wife and Madam Secretary, you can have serialized story elements woven into a case of the week. She's a crime solver, so she's going to have to solve a crime." In July 2015, Adler spoke on how much influence Superman would have on the show, saying, "Our prototype is the way the president is seen on Veep. It's certainly [inspired by] so much of what Julia Louis-Dreyfus' character goes through. Ultimately, this is a show about Supergirl and we really want to see it through her lens."

Casting

For the role of Kara Zor-El / Supergirl, the producers wanted a Caucasian actress aged between 22 and 26 years. In January 2015, it was announced by The Hollywood Reporter that Melissa Benoist would star as the character. Benoist later revealed that auditioning for the part "was a long, drawn-out, three-month process"; she was the first actress looked at for the role, although Claire Holt and Gemma Atkinson were also considered. In the same month, Mehcad Brooks was cast as James Olsen, based on the character Jimmy Olsen. Unlike the comics, where the same character is portrayed as a Caucasian and goes by "Jimmy", this version is African-American and goes by "James". Brooks described this as a form of "intermixing of races", differing from the 1940s where "white things were white, black things were black. Latino things were Latino". In February, Chyler Leigh was cast as Alex Danvers, an original creation for the series. In the same month, David Harewood and Calista Flockhart were cast as Hank Henshaw and Cat Grant, respectively. It was eventually revealed that Harewood's character was actually J'onn J'onzz / Martian Manhunter impersonating Henshaw. In March, Jeremy Jordan was cast as Winslow "Winn" Schott. The character was written for the series as the son of Winslow Schott / Toyman, unlike the comics where Toyman's son is Anton Schott.

Filming

In February 2015, it was announced that Andrew Kreisberg, co-creator of Arrow and The Flash, had joined the series as a writer and executive producer; and Arrow / The Flash and Smallville alum Glen Winter was announced to be directing the pilot. Principal photography for the pilot took place from March 4 to March 29, 2015. Filming locations included the Warner Bros. lot, where Lois and Clark was shot. Each episode cost approximately $3 million to broadcast, which is one of the highest license fees ever for a first year show. Filming wrapped in March 2016.

Music

The score for the season was composed by Blake Neely.

Release

Broadcast

The season began airing on CBS on October 26, 2015, and ended on April 18, 2016. The season premiered on October 29, 2015, in the United Kingdom on Sky One.

Critical response

The review aggregator website Rotten Tomatoes reported a 92% approval rating with an average rating of 7.53/10 based on 71 reviews. The website's consensus reads, "Melissa Benoist shines as Superman's plucky little cousin in Supergirl, a family-friendly comic-book adaptation that ditches cynicism for heart." Metacritic, which uses a weighted average, assigned a score of 75 out of 100 based on 33 reviews, indicating "generally favorable reviews". Max Nicholson of IGN gave the season a score of 7.3 out of 10, along with the verdict, "While Supergirl's first season disappointed in several key areas -- namely its villains and romantic subplots -- Supergirl herself was spot-on, and the story offered several surprising twists (e.g., Hank Henshaw as J'onn J'onzz). Yes, not all episodes were winners, but when the series flew, it soared, especially in terms of emotional impact." Reviewing the season as a whole, Colin Campbell of Polygon criticized the costumes, fight sequences, the ludicrous villains, the predictable nature of the plot, and felt that the title character was not "Super enough", but noted that "unless your interest is in seeing yet another comic-book franchise transferred reverently to the screen they're of only marginal concern." Evan Valentine of Collider ranked Supergirl eighth in his list of the worst and best superhero television series of 2015 and wrote, "Aside from presenting the best Supergirl we've seen in live action with Melissa Benoist [...] it managed to capture a sense of fun among the cast that was infectious."
