For me, the irkiness is not about having a simple room with benches. I haven't seen it in person, but in the pictures, it looks completely half butted. Does Disney have a repro department? They could have added some simple large posters/murals instead of plopping in a bunch of small frames that you have to be on top of to take in and contribute nothing to the feel of the room except tackiness.
EDIT: The bottom of some of those frames are well above guests heads. They aren't there to add anything...just take up space.
