I had heard of Gantz:o, as it was a manga first, and I was pleased to see this particular Japanese 3D CGI style as I am a fan. I had seen this sort of animation before in Final Fantasy VII: Advent Children, in which for me became one of my favourite animated films due to its style.
The motion capture used in Gantz:o as mentioned in the credits, seems like it was used extensively. Despite this, the outcome seemed smoother than other creations, and shows the technology is being used better-than-usual. The movement and body language that was captured are almost completely and unfailingly smooth. During my viewing, I occasionally had to remind myself that it was animated. I kept being astounded by the amount of detail being used for the characters and scenery. Individual hairs on every character’s head moved fluidly, to the extent where you could see a strand of hair moving from a breeze and in closer shots I was able to see singular eyelashes.
There a few unanswered questions especially if you don’t follow the franchise, for example don’t expect any explanation on what Gantz is and why. Despite this it was very good at making you want more. I would recommend anyone to watch this, especially if they insist that animated movies are for children. Trust me they are not!
