We have really had a new manga to talk about in a while in a topic.
Act-Age is a Shounen manga on weekly shounen jump: "Kei Yonagi comes from a poor family. Her father ran out on her and her two younger siblings, leaving her to fend for the family herself. When the opportunity comes to chase her dream of becoming an actress, Yonagi jumps at the chance. Catching the eye of Director Sumiji Kuroyama, Yonagi’s opportunity to shine has come. However, Yonagi’s talent for acting comes from her extreme and innate ability for Method Acting, one that various individuals note as potentially self-destructive."
The girl comes off at first a bit bland her special skill is either to replay a scene of her past or something she saw and using the emotion to act or she delves deeply into her role. By the fourth chapter she was stealing the scene as a side character in a feudal piece because she convinced herself that the girl was really about to be killed by a samurai, and she could do nothing about it.
The director is the eccentric mentor that has loads of experience but is new to the area who wants to use the girl to change the Japanese acting world.
The art is ok most of the time but this one panel is when I finally got interested in the manga. It the scene I was talking about before; she really looks like she is internally destroying herself because she can't save that little girl:
It has potential but it doesn't really feel like a shounen manga (more shojo or even seinen) and that doesn't help that it is a new manga in the most competitive shounen magazine.
