The Economist agrees with me! Kind of

No less an authority than The Economist dislikes Kosovo's flag, too! (see below for image). They have a somewhat specific point for their objection, though: they don't like having "a precise outline of a map," since that makes it hard to reproduce. I suppose the one thing that makes Kosovo's flag distinctively sterile--a lack of symbolism--is the one thing that was necessary, but they could have done better even so.
