In the year 1923, a vampire crisis takes Tokyo by storm. Provoked by the illegal trade of "Ascra," an artificial blood source, the population of vampires begins to rapidly increase within the city. Under orders from Lieutenant General Sounosuke Nakajima, the Special Forces Unit 16 gathers vampires within the military to create a new undercover vampire-hunting unit known as Code Zero.

Leading the unit is Colonel Yoshinobu Maeda. Responsible for locating the source of the Ascra trade as well as capturing and killing vampires, he is pressured into producing fruitful results amidst the growing criticism that threatens to decommission the unit. To make matters worse, the vampires within the unit are struggling to grasp their newfound powers and identities now that they are no longer human. With the world at odds against them, the members of Code Zero must find a way to curb the crisis or otherwise fall victim to their own demonic natures.

Mars Red is based on a 2013 dramatic stage reading of the same name that was written by Bunoh Fujisawa, the sound director for the anime.

Show don't tell

Is one of the first and most important rules of story telling. it's a rule that pretty much everyone knows, everyone understands why it's important, but next to no one actually cares about it.

I mean we all acknowledge that most shounen anime explain what is happening in the fight, while it's happening. and we all make fun of it, but from everything that I have seen rarely anyone actually cares.

there is a certain truth that I have learned from looking at people's takes when it comes to this subject, and that's the fact that the casual watcher would rather have info dumps, ...

Mixed Feelings
[This review is spoiler free!] TL;DR: Mars Red tries to fit a lot of story into 13 episodes--however, they often spend too long on irrelevant bits and sped past the interesting stuff. The main four characters really make this show for me. It's a good show to watch with low expectations but it's not complete brain rot either.

Mars Red has an interesting way with its story-telling. In the beginning, a lot of the character's dialogue comes from screenplays of different literature--which is interesting, but is completely lost on someone on the average viewer (aka me). Mars Red's greatest weakness is their story; the pacing felt ...

I feel like it had potential, but it just falls flat on it's face pretty hard.

You probably know the trope of over explaining things in anime, well
this is the opposite, most things that would need an explanation aren't explained. Be it character motivations or actions, effects, twists.

Because of this, most of the time when there is an emotional moment, you just know that it SHOULD be emotional, but it really isn't.

It's theatrical, which is something you either like or not, but a lot of times it just felt out of place fore me.

Overall, it's pretty forgettable; even though based on the premise and what actually ...
