Nejimaki seirei senki: Tenkyô no Alderamin

Pros: The animation, the music, all is nice. A pleasure to watch.

Meh: The story itself revolves around a war or two, with important background information being thrust forward as needed.

Cons: The one "genius" is always right and the story revolves around him. Similar to Death Note. He's just a magical character that basically always wins. Hard to feel for him though, so the wins feel empty.

Conclusion: Overall it is a decent anime, a good watch, and nicely done, but you're not missing anything if you do not see it. Otoh, if you like anime, it's not something you'd regret watching either.
