I know Spideyboy posted a review and goes into depth about the After-the-Credits scene but here is my take on the movie. Like Spideyboy I was fortunate enough to see the movie at a special screening for military personnel, not just Army personnel (I'm Air Force).
The movie itself is great. Though I am a Thor fan first and foremost I have to admit that the Cap movie is probably the best Marvel movie to date, especially within the Marvel Cinematic Universe. The movie will appease fanboys and non-fanboys alike. Some changes to the story from the comics but nothing so dramatic that it will make you walk out of the movie, of course changes can be expected as they have to update and make believable in the MCU.
My biggest worry about the movie was Chris Evans as Cap but he pulled through. There is no way he can ever be looked at as Johnny Storm again, he is Cap.
Hugo Weaving as Red Skull just might be the best casting of any character in any Marvel movie to include Picard as Professor X.
The rest of the supporting cast was exceptional, everyone played their respective part perfectly. One major surprise, you will know it when it happens.
As for the After-the-Credits scene, just wait to watch the movie or read Spideyboy's description. All I will say it that it was unexpected and totally EPIC.
