 If you liked Soukyuu no Fafner: Dead Aggressor |  ...then you might like Evangelion Movie 1: Jo |
Fafner and Evangelion are kindred spirits, both explore the human elements and character interactions that are forged in extreme situations, employing the mecha genre as a means of developing the young pilots and the ordeals they go through. You are (not) Alone, in its skilful retelling of the first six episodes of Evangelion, is closely tied to the initial phases of Fafner.
