Disagreed, sorry. Lelouch´s enemies weren´t dumb, they were capable soldiers trained for their purpose. Lelouch was a genius of three advantages: He was smarter than the rest. He had a lucky upbringing. And he´s got the Geass. All of that allowed him to outclass his enemies, that did their best to dispose of the threat.
In Aldnoah.Zero, the only reason why Inaho is "special", is because he keeps figuring out trivial stuff, like in this last episode the weak point in the joints of Saalbaum´s mecha. Maye I´m playing too many videogames, but come on, EVERYTHING Inaho did was applying basic videogame boss strategy. And worse, the veteran soldiers around him were absolutely incompetent. That combined with Inaho´s lack of emotion (which, I guess, was only so to make him "unique") made it truly annoying to watch.
@shinta: I´m looking forward to the second season. If both of them stay dead, that could actually make the series extremely interesting. However, Im not yet convinced that they wont come back :/
