Well RaXephon is my favourite anime with Evangilon close behind , I dont really have anything to say thats bad about either of them adoring both of them a great deal.
RaXephon's appeal for me lay in the romance , I adore a well told love-story , and the epic tale of lost love at the heart of the series really held its appeal all the way through for me ( being on the edge of my seat during the final few episodes ).
I also love the way RaXephon's story develops a little each episode, in my eyes there really seemed to be no "filler" episodes , as some key charecter or plot devleopments always occoured in each episode, a smell segmant only being given away sometimes , but then truly epic and moving events ( yes I was in tears at some scenes
) at other times.
Coupled with other things like the beautiful music , the wonderful cast , thats what made RaXephon as masterpiece.
As for Evangilon , I think the charecters made this for me. I felt that each and every one of the main charecters had something to add , they all felt very human to me... which was part of their appeal. Considering I only saw Evangilon this year and after RaXephon , that may well be why I felt RaXephon was better . But I certainly felt the darker, slightly more serious plot of Evangilon stood up well to RaXephon despite being ten years old , I definately think they are both masterpieces.
