I don't know. I haven't watched it yet. Saw the first three minutes and my first thought was "Oh, this is another one of those overly dark apocalyptic things or a mecha thing." I don't like mecha, so I figured I wouldn't like AoT. Another reason why I didn't like it is that it kept jamming my computer. Stupid HD.
However, I need to see this show. I will watch it when I have a chance to sit down and do an uninterrupted marathon, because it honestly looks intense.
