I assume it's partially because of the harsh backlash from diehard fans, since some of the well established lore got changed tremendous. For example: - Durotan and Drakka never died at the Darkportal. That happened by an ambush years later way up in the north of Azeroth. -That's also how baby Thrall was found by the Human Balckmoore, who let one of his servants raise him to turn him later on into a gladiator. -Blackmoore also gave him the name "Thrall" which essentially means slave, his birth name is "Go'el", although I can't remember if that got even mentioned in the Movie. -The last scene of this Movie (isn't shown in this recap) where baby Thrall was in his crip, carried away by the river is geografically impossible since there's no river in the Eastern Kingdom that goes from the Dark Portal all the way up into Hillsbdrad Foothills, where Blackmoore has his Garrison and found baby Thrall. -King Llane also never died at the Dark Portal. He died in the Throneroom, still by Garona though. That's what I remember, probalby find more if I rewatch the whole thing. It's tiny thing's for the most part but stuff like that pissed off many diehard fans. I find it redicolous, since it doesn't really matter. Characters that are supposed to be dead for later on are dead. AND what many tend to forget, this movie has lore material from several books, it's very hard, if not impossible, to follow all of that 1:1, so diviations had to be made. 🤷
