I didn't know whether to commend them both for being so god-damn brave and self-sacrificing or to be angry with them for being liars. Probably the latter. Either way it was a stupid thing that they did.
At the end of the day, I'm disappointed with K for not having the guts to be honest and for insulting Cream's intelligence. I'm disappointed with Cream; for knowing the truth yet choosing to pretend to play along.
Ultimately, I do recommend this movie but be prepared to be frustrated.
