Re: SPOILER ALERT: Anyone bothered by....
No one I've spoken to outside the fanboy/girl community has brought up an issue with it. Last time I saw it (this morning) some people in the audience cheered when the bone claws came out. the whole "why didn't they saaaaave it" stuff is just a fan gripe because of comics knowledge. The scene served a purpose in THIS movie and at the end of the day that's what matters.
Joss Whedon's MUCH ADO ABOUT NOTHING is the cinematic equivalent of Tony Stark building an Iron Man suit in a cave with a bunch of scraps
