I will try to be as vague as possible while still remaining coherent so as to not give away too much.
I liked the movie and it is possible that I am over interpreting the movie but want to address statements that the end is in contrast to the majority of the movie. It isn't, the reasons for the resurrection of the "revenants" and the basic motivations for the zombies is suggested early on in the movie and the movie does provide confirmation of the reality of this motivation subtly quite early. The movie presents the motivation as manifesting in various forms through the characters dialogue, multiple world views interpreting the basic motivation of the cause for their resurrection. It makes what is happening at the end more coherent, the characters various ethical dilemmas and basic motivations manifesting in different forms. The zombies discourse is close enough to resemble the major discourse present in living human society such as love, equality, art, meaning and truth, but the unconscious drive behind these positive terms is something else not human and the majority of them are probably are not conscious of the disparity.
