Turning a memorial to those who sacrificed (some, ultimately)into a splash park is something else entirely.
The designer did that, by installing splashy fountains playfully throwing cool water in every direction. The "splash park" is the main attraction of the memorial.
When I have out-of-town visitors, I send them to the Lincoln or Jefferson memorials. The FDR memorial is a nice place to walk. The WW2 thing doesn't rate. Might as well make better use of it.
BTW, there are lots of memorials that are primarily just list names of the dead, like the Vietnam memorial. They are on town squares, or in prominent spots in most colleges, for the civil war, WW1, or WW2. Most people just walk by them, without a thought.
