We've entered a post-modern age for quite a while already anyway. Since the 80s, I guess. Post-war brutalism and minimalism are having a hard time. My taste is diverse, I can appreciate things of various styles so long as it seems to be some fair quality to me. But as I'm used to saying now, French post-modernism is causing a little harm to the art of design over Paris in my opinion. Here's an example of what I really don't like seeing too much over here, in Issy-les-Moulineaux.

Bad bad taste. Kind of stuff that tried to mimic the local traditional fabric, but in cheaper materials. I give it zero chance to age well. It's a waste of room to me, amongst the worst things developed at the moment.
