Overblown means made far more of than it deserves. Overblown claims, an overblown reaction, overblown prose.
It is a criticism of scale rather than truth — an overblown account may be accurate and still too grand for what happened. Of writing it means inflated and self-important. The image is a flower blown fully open and just past its best.
