The story of Blassreiter takes place in Germany where these creatures known as Amalgams aka Demoniacs other better understood as "robot zombies" due to them being formed out of corpses & can merge with technology. To stop this threat the XAT are formed to combat these Amalgams, eventually the story moves towards this battle of good evil with the XAT members being the main characters however, that's when this story comes across some pacing issues.
For starters, the anime rotates its lead every 4-5 episodes as characters tend to die then we follow our next lead etc. This is good as no character is safe from plot armor, however it doesn't flow neatly at times. One reason is the character Joseph who by ep 13& 14 we learn of his backstory whose heavily involved with the series villain, Xargin. Because of this odd choice, Joseph who should be the center lead makes random appearances in the beginning of the series & even after his story is revealed he doesn't become the main focus. While the other XAT members are alright characters to follow, it does feel strange that the villain's main nemesis is hardly given the spotlight.
Another problem with the show is its symbolism to religion can feel forced at times. Much of the shows deals with revenge & various depressing topics such as suicides & abuse which often creates these revenge situations. It makes sense to speak of religious topics in this situation but some scenes feel forced & preachy.
Overall, the anime itself is interesting as it does take advantage of its sci-fi mythology of Amalgams & certain characters do feel believable. This is one of those rare series that takes itself very seriously to the point where it can feel depressing at times. Other highlights of this series is its OST being performed by Norihiko Hibino (Metal Gear Solid series) & some of the writing is done by Gen Urobuchi (Fate/Zero, Madoka Magica, Phantom Requiem for the Phantom). Blassreiter is unique sci-fi diving into humanity's scorn for destruction, however it would have been better if certain characters got more appearances in the series or a more steady pace in story telling.
