The raised-in-the-wild savior protagonist has been done before, the ship on the run from enemy forces thing has been done before (in at least two Gundams), the pure, all-knowing, everybody-loves-her princess has been done before… There’s nothing new to see here, so enjoying Heroic Age boils down to whether you like the characters or not. I didn’t, so I didn’t enjoy the show and gave up after 10 episodes.
The main character(?) Age is basically perfect. He’s a little wild because he was raised by super-powered aliens, but he starts out knowing all about his powers and all about his mission, is clearly far stronger than anyone else in the universe and knows exactly what to do and when. No doubt, no anger, no passion, no confusion. It’s impossible to relate to him. The second main character(?) Dhianelia, is also basically perfect. Psychic powers, good looks, princess, everyone loves and worships and obeys her and she, too, knows where to go and what to do 90% of the time and her few moments of doubt come across as insincere and put-upon. The supporting cast exists only to fawn upon or unsuccessfully attempt to oppose these two. The ending was a foregone conclusion from episode 1.
It would be have been okay if the action at least was good, but that wasn’t anything noteworthy either. The first 10 episodes had the humans fighting the same bugs over and over again even when it was clear that the humans were useless against them and Age was the only one who stood a chance. Bugs, bugs, bugs, more bugs. Age also fights enemies with similar powers, but since we can never get into his head, it’s hard to root for him when you can’t tell how well he’s doing or how he’s feeling. Maybe it picks up after episode 11+, but I’m not sticking around to find out.
