Battle Royale (Kinji Fukasaku - 2000)

Ok, someone help me out here: I heard that extra blood was digitally added for the special edition, so my question is does the blood look extra CGI-like/fake/whatever in the SE compared to the original? Because I just saw the trailer a few days ago, which i’m guessing was for the original version, and all of the blood in it looked pretty realistic. But when I saw the movie on the big screen at a university a few months back, it looked like it was something out of a video game. But i’m not quite sure what the answer is because the movie was shown from a dvd player instead of actual film, which might have been why everything looked like that.

So…somebody give me answers, please
