I see Alia's point, but that does not mean I disagree with you Upright. The way we perceive something is subjective, and obviously you thought differently of the scene in question. I think they did a beautiful job translating the emotion on-screen through Harry's actions, and I felt their change in the details of events also suited the film. It would have been campy and superfluous to carry on the scene any longer than it had already been, simply to appease the audience of readers, when we, of all people, understand exactly how Sirius's death made us (and Harry) feel. The part of the audience that did not experience Harry's turmoil through the literature likely felt their own twinges of pain; quite a few of them were attached to Sirius as well, just by his presence and relationship to Harry from the preceding films. Three of my close, personal friends are fans of the movies, and have yet to pick up any of the H.P. books. All of them were deeply saddened by Sirius's demise -- one even cried (quite obnoxiously) and ranted about how very unfair it was.
Critiques of the film are definitely welcome in the thread, but if you feel very strongly that the filmmakers made a drastic oversight, at least try to be a bit objective about it, and think for a moment of how difficult a task it was to do what it was they were doing. Even then, if you still feel as if they didn't pay justice to the books, then call it a bad show and move on, rather than make an argument of opinions. Apples and Oranges, as the adage goes.
