I enjoyed the story, yeah I agree the armor could have been more high tech, but it still looked good.
As for who Stark's wife is, that is Bethany Cabe, she was very important in Iron Man's history during the 80's, she was Stark's chief of Security among other duties and was always believed by many Iron Man fans to be Tony's true love, it was fitting that after all the women in Stark's life he would finally be with Bethany.
I too wish they would have spent a little more time on what happened to Iron Man's rogues gallery but maybe the writers felt it would clutter the story, it was nice to see a upgraded Crimson Dynamo.
All in all I would give it a B+, a nice end for Tony Stark and it peeked my interest in the new Iron Man.
