I can see how there could be some upset over the return of KL. What keeps me hopeful is the inclusion of Quan Chi and the fact that he plays a "MAJOR" role in MK. QC is known to be a Necromancer of sorts, so that right there means that we could have potential warriors form all eras of MK, even the eras never put into game or film. See, Quanchi is somewhat of a meddler, he could have created a dimensional rift that allows for multiple realities to intrude on one another, hence Kung Lao's return. I personally believe that this is Great KL opposed to young, y Kung Lao. He somehow escaped from the netherrealm and seeks to defeat his nemesis Goro in battle, there by avenging his own death. Alternately, If Quan Chi can bring back Warriors, who's to say that the forces of light haven't brought their own champions along/ back to do battle with Quan chi's powerful army of wraiths? I like the Fact that KL is included because it opens the door for endless possibilities story wise
