I am not sure that this is not the best movie ever. For one, no movie has ever entertained me to this extent. It had everything cerebral entertainment with all the probing and layer by layer removal of all those things that hide our basest human instincts, along with the revalations of hypocrisy you encounter along the way; brutal violence and eye candy explosions. Decent martial action, excellent if you want it to fit in with Batman; fantastic character development; engaging story line. Allf of this was fit in to a world expertly crafted in the first movie.
As far as the arguments concerning the parallelism to the Iraq war and current fights for freedom, I don't see the point. Bringing up the joker, in any portrayal of him I've ever seen, brings up the idea of chaos. It's necessary that terrorism and chaos be brought up if you want to do a portrayal of the joker that does reflect what the joker is about. Even if you don't call it terrorism, that's what the joker has always done. The comment the director made about the parallels to the iraq war, was based on that chaos. Parallels to any other war can be made on that basis. So no it's not really a political statement that was made with the themes that the movies portrayed as relates to the joker. It's just that, when you speak of the joker in general, those themes come up, and they relate to other situations where chaos prevails.
As far as the cellphone thing is concerned, I do agree that this type of spying ability is something the Batman almost always had in the comics, however, Lucius's reaction to it, is DEFINITELY a political statement, and all I could think when I saw him react that way was "you fucking pansy". Not that that has anything to do with where I stand on things irl. It just felt like, something that broke immersion for a second. That's about the only part of the movie that did that though, because it had no precedence in the beginning of the movie, or the first movie, and wasn't further developed. Everything else was great.
