(10) Adamantium's origins were somehting else which made sense. When I saw these mutants being put in a team together, I was thinking, hmm, Stryker needs some extra motivation, as a character, aside from just going around and killing stuff. Giving him a quest, which just so happen to also link into what would later facilitate Wolverine's transformation, gave it a neat dynamic, I thought.
Ultimately, no casual viewer's going to give a damn where the heck adamantium came from. :)
(11) I thought Wolverine went through some interesting emotional developments, personally. I especially like how the female character was used against/for him, too. The betrayal/love/manipulation angles came across as more cleverly done than in many productions I could name.
(12) I kind of actually liked it a bit more than 'Star Trek'. :) If you've got trouble with the deviations from source material in this, then you'll hate that! XD
