Sentence:  It's contrived and <WSD>flatfooted</WSD>, and neither Loy nor Powell enjoyed making it, despite its bang-up finale: a free-for-all wedding featuring two brides (Margit and Irene), two grooms, a confused preacher, quite a few drunks from the bar next door, and a maximum of conmmotion -- all crammed into Charlie's tiny trailer in a Capra-esque crowd scene. 
Meaning of the word marked with <WSD> tags:  Blunt and unsubtle; lacking finesse.
