The story in Sanakrea is pretty original and adds a sort of... whacked out and comical spin on romance by adding the whole "zombie" concept to the mix. However, watching the series as it came it weekly couldn't have been more frustatrating than anything else, as it often jumped around and it seemed to add in filler or stary from the main story which was left at a natural cliffhanger. Another thing that was frustrating about the series was that it seemed to preogress really slowly. Like all typical anime that are adapted from their original manga or light novel counterparts that are still ongoing, Sankarea didn't have a solid and final conclusion. Actually, it barely had one at all. In fact, watching the end of the series probably would have left the viewer in confusion, as it did for me. The story was something fresh and different, but it simply lacked correct pacing and timing.
Aside from the story, the animation was interesting. It focused a lot on background and scenery, yet the characters themselves seemed to be simple, but good enough for its era. The sound was pretty mellow and nice, but I was a bit disappointed that it lacked the same remembrance and flare that the composer, Yukari Hashimoto, had previously done for the soundtrack for Toradora!. The opening, "Esoragoto" by nano.RIPE was upbeat and interesting, but it lost its appeal after a while, but the ending, "Above your hand" by Annabel was a simple classic for me, and is quite easily one of my favorite songs from this year's anime. The characters were... well... I can't help but say somewhat dull. I mean, each and everyone was unique, but again, they failed to give the story flare and it always seemed like this was a gray anime. I mean, it didn't ever bring out a happy feeling, and it was sort of always shady. But perhaps that's what the authors of the manga were shooting for, but it didn't seem to work all too well on screen.
Overall, I give Sankarea a 7.5/10 simply because I could see where they animators were going with this show, but they lacked the will to do so. I have not read any of the manga, but I feel attached to the series enough to give it a shot when I get some spare time.
