Reminds me of something written by James O' Barr.

I don't know if it is just me, but this reminds me of the crow. I can't help but feel this film takes a lot of inspiration from Iris's story the first female crow and the 3rd or 4th crow. ( comics) ..., take away the crow and rename iris Zoe and put in Indian themes ( although one crow had that) .., although iris was killed with her unborn child.., Zoe wasn't pregnant as far as we know. Iris was a crow that wasn't really an immortal and had a problem with decaying flesh just like Zoe does in Avenged.., then there was the 2nd crow who was an Indian who was killed with his family by confederate soldiers, then came back in the future to get revenge on the soldiers ancestors , or the soldiers reincarnated. The director of Avenged had to read the crow some of the similarities are uncanny.., maybe he used ideas and rearranged them in avenged to avoid getting sued... Idk... But there's alot of similarities here.
