And yes the 60s is not only EVERYWHERE in the show via references, pop culture and musical, but also in the way it was written to be performed. And one thing that really doesn't work when you try to ground it and make it played for the real life moment to moment is the abusive boyfriend. Not to mention that the show loses a lot of the comedy. MJ especially seemed to be directed to (or allowed to, which is also the director's fault) act the role as if she were in a ground real life scenario every scene, or at best a grounded tv sitcom.
It just makes no sense and shows a fundamental lack of understanding of the show on the director's part.
