Gia leaves a mark on the viewer. I know nothing about the real Gia (pardon my ignorance) but I could feel her in Jolie. I think she has acted superbly, probably she identified with Gia. The interviews of people who knew Gia actually weren't enacted that well and seemed a little made up. But in Gia, one finds the traces of that wild -tender friend, which I guess we all have. The movie falls into the category (though at a lower rank) of 'Trainspotting' and 'Requiem for a Dream'. The portrayal of the female love and the way Gia wants to be the man is quite nicely shown. I just wish that the movie had no interview format and had let Gia to tell her own story.
