Boko wa Imouto ni Koi wo Suru was very interesting anime. It was something that I enjoyed very much, but at the same time just wanted them to shut the fuck up.
Story: The story could have been more original in all, but I like the base of "brother x sister."
Animation: absoloutly terrible. It seemed the animators had no idea what the fuck they were doing while designing this anime. The whole fucking OVA made me want to smash my laptop because of how terribe the animation was.
Sound: I had nice sound. The only issue, I prefer dub over sub. The voice of Iku made me want to shove my head in an oven. Most annoying voice ever. Otherwise, I had no problem.
Characters: Yori has one mother fucking creepy obsession with Iku. Yori wasn't very well developed and seemed to have other issues that were "off screen" you might say. Iku on the other hand, I absoloutly hated. Worst character development ever. She forced herself to agree with everything that Yori said, leaving her to look like the true idiot she was.
Overall: Overall, the entire thing was tolerable. If you're into that kind of stuff, great. I have no other say in this. So now my rating for this would be a 6.4.
Strangest taboo ever...
May the force be with you...
overall score: 6.4/10
