Looking at this shot again closely and ignoring all the camera blur as much as you can...
There is definite obvious scuff/dirt marks all over the place. The windows, the floors, the desks, the dark trim on the walls.
But it does look "too clean" on all the brighter surfaces.

In the original it was an old school that looked like it had never been properly cleaned before.
Now it just looks like any random old school. Which makes it more lame....which could actually work in the end.
