No spoilers. Don't listen to the negative reviews. 99% of animes with this type of animation have a bad rating just because of that. This is an anime with a plot that, despite being cliché, is well built, fast and develops perfectly over 8 chapters (I wouldn't have minded seeing up to 12). If you like sci-fi, here are elements that fit very well: space, alien beasts, energy sources, robots and futuristic weapons, military, among others. I want to highlight two anime mechanics that I like: the first, how the chains of command are continually challenged, both among the military and with respect to the prisoners.And secondly, I quite liked how they play with the element of the pregnancy of one of the main characters for the development of the plot: it is very well implemented and is important for the evolution of the story.

In short, and most importantly, the series is entertaining, if you like this genre. I give it a rating of 7.5, but I leave it at 7 because the anime is just "good", I wouldn't call it "very good" either. Additional note: a very interesting series to watch along with the anime "exception" which was released on netflix almost at the same time as "make my day" with which it also shares the genre of sci-fi, space and futuristic elements as well as reflection on life.
