Buric's performance as Milo

I liked the third installment of Pusher, but not as much as the first two. The main reason for this is the performance of Zlatko Buric as the lead protagonist, compared to that of Bodnia and Mikkelsen in the 1st and 2nd part respectively. Buric has a much larger role to fill here than previously, so it makes sense his attributes as an actor would be more pronounced this time around. Nicolas Winding Refn seems to let his main characters make up some of their own lines and comments to make the interactions look more spontaneous, which I think is really good and lends itself to the nature of films describing the metropolitan underbelly with the semi-literate criminals and whatnot (other European directors do this as well, e.g. Gaspar Noe). However, I do not feel this approach suited Buric. The storyline takes him from at least a somewhat-in-control dealer & distributor, to an insecure, rambling mess of a middle-aged addict. However, to me he seems confused & rambling from the very beginning. In fact, I got this impression from him in a few of the longer scenes he had in the 1st Pusher as well. Whereas Bodnia and Mikkelsen come off like the characters they are portraying, Buric looks like a guy trying to play his character, if that makes sense. Buric's face complete with the greasy hardo is good for a gangster at first glance, but the control he has over his expressions, and ESPECIALLY his voice acting is just plain unconvincing and bad for me. I would actually like to know the opinion of Danish & Swedish people who saw the film..? I think that Buric is somewhat redeemed by his apparently bad Danish, so my understanding is that his rambling and verbally unconvincing "style" is attributed to him being an immigrant & not a native Danish speaker. Is this about right? Just to clarify, I completely understand Buric is not nearly as experienced an actor as Bodnia and Mikkelsen are, but this is still part of a great triology, and just as the 3 films will unavoidably be compared to each other, so will the lead actors. Also, Buric was actually helped by the positively terrible performance of the actress playing Milena because he shined in comparison. On the other hand, I thought Radovan was very good, as was Mohammed, so nothing against amateur or semi-amateur actors getting the roles here...just Milo didn't quite get there for me, which is kind of crucial for the film overall.
