You like all the action components of an anime, but you hate how predictabe everything is. Code Geass breaks through these pitfalls of most action anime:
1.) The story is thrilling and contains twists and turns that will constantly surprise you. The characters are each perfectly flawed such that they are relatable.
2.) The artwork, although very bishounen-esque, is unique. And avid fans of CLAMP will be pleased at the character art.
3.) It contains a bit of every genre: Mecha, action, drama, bi-shounen... You name it.
All and all, Code Geass is perfect for any fan looking for something highly emotional and brilliantly fast paced.
