It's worth noting that 'Paradise Lost' is the sequel to 'King of Eden' and a series, 'Eden of the East',came before that, so viewing this as a stand alone film might be a little confusing, and is not recommended.
However, as a fan of the original series and first film, this is a decent conclusion. The quality and attention to detail of the animation is fantastic, the characters as well developed as they were in the series, and my attention was gripped from start to finish.
Its certainly a fitting conclusion to the Eden of the East franchise, however it does have a few loose ends not fully explored, but for the most part, it reaches a satisfying conclusion.
