It wasn't enough to have Anakin born on Tatooine and have a senario where he was inspired to go on some idealistic crusade (clone wars) with Kenobi...instead we have a plot where Anakin is turned into a 9 year old immaculate concepted slave boy with a high midichlorian count

There's no evidence one way or the other that Anakin's conception was immaculate, or that the phrase even has any meaning in the Star Wars universe.

and because his mother was killed by Sandpeople, he is quick to turn into a child serial killer for the chance of saving his wife

Serial killers kill for personal satisfaction and have a waiting period between kills. That doesn't describe Anakin. If you want to characterize his kills as murder, he's a mass murderer. Even that's not entirely accurate, as he was taking orders from the legitimate head of the Republic and Jedi have never been shy about performing extrajudicial executions -- the killings were probably quite legally defensible. It's hard to tell for sure, but given the way the Jedi hack-and-slash anyone they choose, they probably have de jure broad authority to use force in the accomplishment of their missions.
