then suddenly turn into Pagans during the final act for the sake of of a horrendously mis-handled ritualistic sacrafice, which doesn't so much mirror the original as show it through a broken, funhouse mirror.
The "Pagans" claim that the main character is dying a as a martyr, even though in this version his beliefs are only very vaguely referenced and they really have nothing to do with his death or his reaction to it.
Furthermore, this was supposed to be the great sacrafice that was going to save their crops, yet the movie ends with the lamest attempt at a clever scare to grace the screen in quite some time where the Pagans send their women to the city to lure in more sacrafices.
So in other words, the filmmakers ideal depiction of Paganism is repetitive, excessive sacrafice even when the sacrafice to appease their gods has already been made, purely out of their love for sacraficing people; and also savagely torture the sacrafice prior to the occasion when it serves no purpose whatsoever in regard to the sacrafice other than making it more excruciating.
There's also very little explanation as to why this man is the ideal sacrafice. In this film, he pretty much is because he is with an excuse tacked onto the end of it that's more of an elaborate "haha we gotcha!" writing scheme by the filmmakers than something that has anything to do with the spirituality of the Pagans.
Basically the entire film can be summed up as the filmmakers coming up with one inane plot device after another just for the sake of driving a story that makes no sense and has no point forward with the answer to why these things are happening being nothing other than "Because we wrote it," and the answer to the question of why they wrote it being, as shown by the film, "We dunno."
