The concept of Wolverine Origin seemed pretty spacious. The acknowledgment even mentions this. Why tell Wolverine's origins now? The advantage of comics is if a terrible story is told, we can always just retcon it or send it down the memory hole. (Like the rework of the Punisher's origin where his family was killed in a human sacrifice by demons and he was given angelic superpowers. As far as I know, it was never officially retconned, but everyone ignores it, which amounts to the same thing.)
I am a relative newbie to the Wolverine party, but my understanding of the character is that his central drive is the continuing struggle between civilization and savagery that rages within him. Wolverine seems to struggle between different levels of this dichotomy: noble savage, failed human, barbarian and bloodthirsty killer. In Origin, he starts as a pampered wealthy boy with a pet puppy and crippling allergies. He seems to have a psychotic break after seeing his father and mother die on the same night and refuses to speak to anyone for a long time. From here, he grows into a rugged frontiersman, which seems to suit him. Civilization and tangled relationships blast through and he falls further and goes to live in the wild, turning his back on humanity entirely.
Now I'm sure there are loads of crap Wolverine comics, but between Origin, Weapon X and Wolverine by Claremont and Miller I am going to tenatively look for more Wolverine stories to read.
