The anime's score, while probably not only because of the CG, speaks for itself. It was jarring to look at, it was distracting, it wasn't fluid, and basically everything that could be wrong with it was. On the other end of the spectrum, you have anime such as Hand Shakers, which had absolutely horrible CG. There are countless more examples of this being the case. Clearly, in those cases, it was done well and there was nothing wrong with it. Fate/Zero & and Fate/Stay Night Unlimited Blade Works, both praised as some of the most well animated series, used quite a bit of CG. There is, however, something wrong with poorly done or implemented CG.
