It definitely struck a chord with me, also. The romance in this film is probably the best I've seen in a comic book film, and I think a part of the reason for that is that it is doomed. He gets frozen and they can never be together. All their moments together are bittersweet, because the audience knows what is coming. I know others think it was a little too somber of an ending, but it was nice not having a perfect cookie cutter ending. Personally, I would have liked a scene at Peggy's grave, but that actually may have been too somber.
