Finally watched Once the movie, two weeks after watching the musical at Wharton centre on MSU Campus, and like all other original VS arrangements, the original almost always win, i.e. I like the movie so much more.
The pace in the movie is much more natural, no more musical silly scenes in an attempt of creating a humorous environment, and the ending is not as abrupt. It's the same ending (and story line) in both the musical and the film, but the way that the movie approached it just feel more humane to me, on the sad side.
<Once> is actually quite a realistic romance film. Not one single kiss (one gentleman kiss doesn't count), no "hanky panky" scene. Just one "noor ho tebbe", which I have to look it up for translation on the internet after the film to confirm the answer, makes me feel as stupid as Glen Hansard. Brutal, but brilliant.
On the side note, this is the way to show life's reality, instead of Richard Linklater's attempt in creating a "reality" in <Boyhood>. For me he just failed miserably, and I have not idea why did I even bother to watch the film. Using the same cast for 11 years is a brilliant idea, I do admit that, but so is <Harry Potter>! I'd rather watch the entire <Harry Potter> again than <Boyhood>, IT'S JUST BORING!
