I binged watched this series on Netflix as I was hooked on the first episode. It's both funny and sad to see the daily challenges in Retsuko's life. Retsuko is both overworked and isolated and the series shows her transform into a more confident and content person. The ensemble cast both adds to the craziness of Retsuko's life but sometimes also provides her refuge. One of the central themes in this show is how everyone is not what they first appear to be. Most of the characters get moments in Season 1 that show them as more than just caricatures in Retsuko's life and I found this to be one of the most endearing aspects of this show.
Besides just being a good show, it's also a wonderful show that depicts modern life through a young woman's perspective and the specific challenges related to women in the workplace.
If a funny, endearing, sincere and wonderfully feminist show is something you're interested in then I can't recommend "Aggretsuko" highly enough!
