I think it is the best ending i have ever seen. However the only thing bothers me is that both Noob saibot and the orginal sub-zero were both in mortal kombat trilogy.

the only thing that really gets to me is the fact that the old war of 'was sub-zero in more mortal kombats?'... (o_o), my my, though i must admit that was quite a plot twist, but smoke betraying sub-zero aint a surprise, i doubt sub-zero's mk3 ending was cannon to where he saved smoke.
