I hate the rampant Wei hate in this film

So biased towards shu and wu. I wish someone would make a movie that is sympathetic to Cao Cao and his family and friends. Wei had the most loyal officers of all the three kingdoms. And some of the bravest people. Pisses me off that Xiahou Dun was reduced to like 3 lines in this whole movie. And he didn't even have his eyepatch! wtf? by Chi Bi, he had lost his eye. Yet in this movie apparently that never happened
