Angles Of Death (maybe spoilers)

What do you think about the anime ANgels Of Death/Satsuriku No Tenshi, until now? If you have played the game, do you think it's accurate? Cus until now i think it is... but some things are not as well. Do you thnk that they will stick with the original ending? I see that they're trying to make some changes to it... idk. Wdy think?
