Indeed. Round about "Like a Virgin" is where it pales for me. Too much repetitive up and down. Too many Madonna songs. The ending is muddled and incoherent.
Also I am not keen on the plot. I always side with the Duke. He is deceived - why couldn't she be honest with him? They are just a couple of evil low-life taking the Duke for every penny they can while screwing each other's brains out.
