an interesting concept vampirism have something to do with a virus . ( but do several time by now ) overall the movie be too long and drag a bit . the editing could have be tight . i be sorry to hear about the problem with the credit . maybe the movie be rush to market . the lighting be too dark in place . but the bad technical problem be the audio . the level be good enough to hear the dialog and but many of the interior have a echo sound to them and which be very distract . either they be not careful in the recording and or the sound mixing could have be well . also too much background noise get through . the should have get someone to do sound effect for the martial art scene . the tinny clank of sword hit together be not the sound of an epic battle . especially in the combat scenes the edit need to be tighter . also the acting be a bit flat . i be sorry and but when i see that the same person writes and star in a movie and in my experience it be a red flag . but it be a good effort so i give it a 4 .
