Terrible Depiction of the 1970s

I have seen my fair share of 1970s movies that were actually made in the 1970s and this movie was way off. My biggest problem would be the way the actors spoke. They were using their 21st-century voices when in the 1970s people spoke noticeably different. The leads actors' hair was bad too. There wasn't enough bounce to it. It was too stiff. (kind of like the acting!) . This movie could have easily have taken place in 2016 aside from the wardrobe and cars. I actually forgot this movie took place in the 1970s at certain points in the movie. Specifically when I saw Kim Basinger and Russell Crowe's characters on screen. If you see an actual 1970s movie then you will notice exactly what I'm talking about.
