Meh, so long as the angels remain hallucinations and it doesnt become a god vs devil type of film it might be ok. I remember watching a fan-film of max payne which had nickleback in the background music, that looked/was much better than that trailer ><
*edit*
Ok, not as good as I remember, but still, I think I prefer it to the trailer...
