So what went wrong here?
Well first of all, there is a serious lack of plot progression in the first few episodes which IMO should be the most important of the story. The first few episodes are the "hook" that will make the audience decide whether they will watch the next episode or drop this show. The director and the writer failed at this part. Yes they made a decent 1st episode but the succeeding ones are almost carbon copy of the 1st one with minor variations. Example: Saya eats her breakfast, goes to school, talks with friends, a random but vague hint/foreshadowing appears and then time to kill the monster of the day. The show basically wasted 3-4 episodes before getting to the interesting part of the story.
Second. The story's pacing. The director and the writer purposely extended a rather simple story by dragging or adding scenes that doesn't necessarily contribute to the plot. Blood-C's story(including the upcoming movie) can fit in a 12 episode format with proper direction and storytelling. There is no doubt about it.
Third. Incohesive story. Blood-C is a mystery story. The plot revolves around the "truth" about Saya, the monsters and the town. In order for a mystery story to work the writer must occasionally drop hints at the right time that will create interest or excitement to the story and at the same time reveal a part of the plot a little bit. The show failed at creating interest by hammering the audience with repetitious vague hints/flash backs. How many times have you heard of "the contract" or "the promise that Saya made"? Did it enlighten you a little bit when you heard those phrase or did it leave you clueless and confused? Only in the last few episodes have we learned about the truth. Was it satisfying? Maybe. Are there any audience left that will watch the "explanatory" episode? You know the answer.
Overall I enjoyed the action and maybe the fanservice but the story just bored me to death. So in conclusion, Blood-C is one of those anime that could have been something unique and interesting but end up bad.
