The story hasn't change much from the original, and there's nothing wrong with that. The animations are splendid and beautiful to watch because how realistic and how well animated the movements are, but I don't think this works really well for The Lion King. The character's faces fee expressionless for me, because how realistic they are. That's become a huge bummer for me to recommend this movie to watch, especially for the original fans.
I'd recommend it just for the sake of appreciating how well made the animations are, sorry Disney.
PS: Scar without Jeremy Irons' voice is just wrong
