Thoughts on modern Architecture is a pretty big subject to define from one picture. There are countless incarnations of modern architecture all over the world. I will just compare the image that you attached and than the construction image that is shown a little further down in the thread.
The computer generated image has an overall form that I think it is trying to project. The problem is that the form is made out of a mess of intertwining linear steel that projects the overall form of the building but has no other interest at all. It just look like a mess to me.
The construction picture shown later in the thread has some of the same intertwining elements in a more repeating but separated
fashion with a variation on each that helps create more interest to the eye. I would hope that the way they actually create the skin of the building will help to keep interest on these elements and not distract by being a little more subdued so that these objects are the focus of attention and not distract from them by creating more of the intertwining mess. On there own the elements are not a mess, but if you make the entire building the same it will be a mess.

That is my opinion anyway.
