My opinion is, if you are going to make a version of something from other media (manga, game...), you have to be faithful, creativity here is not much welcomed to me. The chances of ruining it are high. Leave it for original work. So, in terms of adaptation, Kyoani deserves credits. They do not inovate that much (that's good) and make it pretty. That's enough
I think you are referring to the fact that Kyoani just do adaptations and not original stuff...
But we are talking about higurashi here. The creative work is done, no need for more.
Anyway, don't know why so much fuss, it won't be Kyoani that will do it...
