Unless you can really groove on costumes and set design, don’t bother.
The best characterisations come from the characters based on real people, who admittedly Cameron took some pains with to ensure the actors physically resembled them. Cathy Bates was lovely as Molly Brown, and both she and Victor Garber as Thomas Andrews get a lot of mileage out of little screen time.
The two main characters and the plot… I’ve come to subscribe to the theory that old Rose is an unreliable narrator and made the whole thing up. It’s the most charitable way of viewing it. The whole idea of a shop sinking so horribly being a sort of “liberation” is just wrong.
I saw it because my ex was curious just what the hell all the money had been spent on.
