Neon Genesis Evangelion, Fullmetal Alchemist: Brotherhood Recommendations
Although as a genre, they are different but deconstruct them they are truly very similar. Both supposedly anime that are aimed for boys, both transcend their genre by providing plot narratives that tackle universal issues that slowly become personal as the both series progress.
They're bouth about a force that goes to God, but Neon Genesis is about mecha and FMA is about alchemy...
FMA Brotherhood and Evangelion have a lot of common discussions through their development: the value of human life, human communication, the confrontation with god, moral and ethics, life and death... Both are great works of art that have humanistic messages and deep philosofical thoughts, and, for that, both are a must see
Both have symbolisms and philosophies.
