a very daring theme

A daring story with an unexpected pairing.
I finished watching questioning why would the actors accept such roles to begin with. like what does this movie add to their career!?I'm very disappointed in these two in particular,I feel like they ruined their image with this movie.I've always had respect for them.
About the movie I must say it was fun in the first half but the second she started tying the guy up,things gets uncomfortable and I only continue watching to see what's going to happen next.
