@CaptainCyke: Quite frankly, that ending seems bloody stupid to me. I think they ended it quite well, thank you very much. Your dapper ending would appear horrible to non-comic readers such as my Auntie Christineth, who would have no bloody clue who the hemmys were " Sharon Carter ", not to mention Mr. Mace Windu with the doo-hicky around his pupis. To add to my documentation, the "spoiler warning" seems quite unnecessary, given the fact that most people reviewing this web article have the knowledge that Windu was in Iron Man 2, as well as Thor. Furthermore, they would have knowledge that Captain America would appear in the Avengers, with Windu and the other heroes. From there, they could make an assumption that Windu would most likely appear in The First Avenger. As for Peggy Carter and being awoken in the future, anyone on this site would know Cap was frozen during WWII, and awoken from his slumber years after. So, that would make it a no-brainer that it would appear in the film. Comic readers would also have knowledge that the good Captain was in kahoots with Peggitha. Well, I best be off. Cheerio!
P.S. I am not British, nor do I have a British accent. To add to that, I do not have an "Auntie Christineth"
