In LOTR, Orcs are just plain evil ugly creatures with zero personality and any sort of depth. In Warcraft they are their own people with their own diverse needs, interests, emotions, AN ACTUAL SOCIETY. lol For me Warcraft is better. Despite some of it's flaws. Even the bad guys in Warcraft have something interesting about them, well mostly, not like Deathwing who is just this evil, mad and angry dragon out of the blue.
