Julio Blanco, the charismatic and manipulative owner of a family-run factory of industrial scales in a Spanish provincial town,[8][9] meddles in the lives of his employees in an attempt to win an award for business excellence.

The critics consensus reads: "Led by Javier Bardem's charismatic performance and writer-director Fernando León de Aranoa's sharp humor, The Good Boss is a workplace satire worthy of promotion.

[35] Guy Lodge of Variety gave the film a positive review and wrote, "Fernando León de Aranoa's corporate satire is too long and languidly paced to pull off its farcical inclinations, but it gets by on its star's magnetism.

[36] Raquel Hernández Luján of HobbyConsolas gave the film 90 out of 100 points, deeming it "excellent", praising the "sharp script", the (actors') direction, and the "careful mise-en-scène".

[9] Mirito Torreiro of Fotogramas gave The Good Boss 4 out of 5 stars, highlighting an immense, eminent Javier Bardem in one of his most dazzling performances to date ("he is, quite simply, the movie"), also considering that Aranoa offers viewers a dark comedy displaying a grim portrayal of labour relations.

[39] Reviewing for Cinemanía, Santiago Alverú gave the film 5 out of 5 stars, writing that the political commitment from León de Aranoa and Javier Bardem mixed with the expressive talent of both of them have created a highly entertaining vindication, concluding that "except for Amancio Ortega, the whole of Spain should like it".
