Yeah, I can understand restricting AoT, it does get gruesome, even in the first few episodes. But it also has that "Who will be gone next, when, and how?" that makes it so suspenseful, which is part of the appeal. But it's been so long I need to reread/watch it at this point. Hm, I'm not sure what I would recommend, I'm not too big on anime either. I watched plenty but not that much, really.
