TL;DR – It sets up an interesting conundrum about a world of combat AIs and then revels the story.
Post-Credit Scene – There is no post-credit scene
Disclosure – I paid for the Netflix service that viewed this film.

Jung_E Review –
We are thankfully back at the point where there are multiple new films every week. While this is great, it leads to the problem of trying to find which one of the many you take the time to watch? Well, when you hear that the creator behind Train to Busan has a new film out, that choice becomes quite easy.
So to set the scene, it is the far future of 2194, where humanity has wrecked the planet, and after climate change leads to drastic sea level rises, most humans escape to shelters built near the Luna orbit. With those left on Earth working in the factories. But this respite would not last as some banded together to create the Adrian Republic waging a decades-long war against The Allied Force. Everyone is trying to find a way to win the battle before humanity is wiped out, and for Yoon Seo-hyun (Kang Soo-youn), that weapon is the cloned android of a great leader of the past Jung_E (Kim Hyun-joo), or as she knows her as, mum.
