I disagree with the sentiments of many posters here that Weyoun is uninteresting simply because he is loyal to the Founders. How is that different than every other character being loyal the the Federation?
Weyoun expertly conveyed a huge range of emotions throughout the series. Often several different ones in a two minute scene. Weyoun shows more versatility in the one scene talking to Sisko aboard DS9 in the Call to Arms episode (the scene where he talks of starving Cardassian children, and also gets PO'ed [You will not allow?!] at the Sisko, and then becomes gentle again etc.) than Khan showed in the entirety of Space Seed + WoK combined. Weyoun puts into action, visually and with his voice, all the diplomatic and persuasion skills that Khan is said to have yet never shows any scintilla of actually having.
Not to mention Weyoun's interest in learning to understand art, the ability to appreciate the different textures of food, ambitions to take control of earth, and all the empires he's conquered with his tongue instead of the sword, which is what a truly wise conqueror does.
