I kind of like it for several reasons. For starters, it looks like a much older flag, which means it looks pretty nice flying over historic structures and such.
It also uses muted tones of primary colors, which means it's bold and recognizable, but not an eyesore.
It incorporates the double eagle of flags nearby, which makes it nice on school children trying to place it on the map, but it seems to buck the trend of other new flag designs which look to me so much like a bunch of company logos from the 1980s.
So kudos to whoever designed this one!
