Yes, I looked at the photos closely. Look at those photos again, they are all extreme closeups of minor stuff. MAYBE the beads are out of whack, but there is nothing in those photos that show they are. Those shims, hackish as they may appear, show that the guy hanging it was at least working to get the geometry right. I've seen metal bead put on beautifully that couldn't be finished. You may not like staples but USG says crimp, nail, or staple: not drywall screws. None of the photos are pulled back far enough to see the screw pattern. So, maybe it wasn't secured properly, but there is no evidence.Did you see the bead? And with how they hung it im not so sure it glued or secured properly.
