The images speak for themselves.
While I am thoroughly enjoying the comedy found in Boku wa Tomodachi ga Sukunai, I am very disappointed at the level of animation quality shown in the 8th episode. The above images were taken from the first half of the episode and already showcase everything from misplaced eyes, to blocky hands, wooden arms, squished heads, and the “where am I looking?” stare. Anime International Company (AIC) has plenty of experience producing anime, going back to the late 80’s, so I’d expect them to have a certain level of quality. Unfortunately, it seems that their newest division, AIC Build, is not keeping up with the rest of the company’s animation staff.
The AIC Build division has only worked with one other anime before: Ore no Imouto ga Konna ni Kawaii Nake ga Nai. I suspect the division is simply inexperienced at animating episodes consistently with a tight schedule, but I don’t claim to know the inner workings of the company. My hope is that whatever happened here gets corrected soon. Boku wa Tomodachi ga Sukunai is a profoundly hilarious anime (every episode so far has made me laugh), and I would hate to see it ruined with bad animation.
EDIT: By request, I have marked up the images above with what I thought was wrong with them. You can see the marked-up images below, just click to enlarge.
