I agree, it's pretty early to judge Zeref since we know we have more to see from him. The thing I felt about him and that I think others did to was that the build up to him did not ultimately construct the character we saw. If you're going to describe the most evil Mage in history who created numerous demons and decimated the world, why, when you finally introduce him, would you twist it up by making him a sullen teenager with no (initially) demonstrable Magical abilities? Maybe 40 chapters passed before Zeref actually killed anybody and then too, it was by accident. Killing Hades was nice and we finally knew a bit more but him at that point also raised a lot of questions, like his real connection to Acnologia. If Mashima was trying to put a twist in the story, it's my opinion that Zeref was the incorrect way to do it.
