Gantz Criticism?

I saw a very bad review at AnimeNewsNetwork about Gantz. It critizised Gantz in everything from the characters to the story to the fighting scenes. The reviewer critizised the character development while he/she was reviewing vol. 4 and 5! Why the heck will you want character development in vol. 5 while you have another 23 volumes to develop your characters. Kurono first starts out like a jerk and develops into a hero. The story is fantastic. First its all missions and the characters develop and then the grand finale starts. The fighting scenes are really cool and detailed better than if it was animated. At the end of the review he/she wrote "Oku still can't draw". What the fuck? The art of Gantz is spectacular. It's detailed. The art of Gantz is one of the best art out there. Only surpassed by the art of Berserk, Vagabond and so on. I was shocked by this review. Looks like some people just don't like the good stuff. Just hold on to your Pokemon Mr. Reviewer. People please don't believe anything in ANN reviews. I just go there to get news thats all. Thats the only thing their good at.
