platitudinous

Everyone this side of Charles Krauthammer agrees that Romney was general and platitudinous and not that engaged.

It used to be axiomatic, platitudinous, that Frenchwomen dressed better than Englishwomen.

Now Poussin is, or appears to be, in many of his works a dramatic painter, and for us his drama is platitudinous.
