Leonard-esque...

I just find this concept so irritating...the other day i bought a biography of Leonardo da Vinci... never having heard of the author before i decided to do some googling to see any reviews...and there it was - the comment - "the book is definitely leonardesque"...how can a book be that....how can anything and everything be "esque"...i can understand "picturesque" but leonardoesque ??? exaggeration and pseudo intellectualism at its best...now i don't want to be judgemental...people do have right of expression...but do we have to say things even when we don't have anything to say...
