I'm torn with rating this film, so I'm going to write myself into a number. Cute, but silly-cute. Awkward is a good word for parts of Hysteria. Entertaining, but in a corny way. You think a story about the invention of the first electric vibrator, that's going to be graphic or hilarious, but it was neither.
So the movie is about giving old women orgasims, and Maggie Gyllenhall's character flaw of caring too much/being too charitable. It tried, and fails to push upon women's issues: "hysterical" women, (ie., women who are overworked/under appreciated/tired of feeling like slaves/under "loved") seek medical treatments for getting through their ruts. The movie sounds dirty and the R-rating certainly marks it as naughty, but it's reserved.
Hysteria's entertaining, maybe even cute, but not great. It does lightly push women's suffrage in a quirky manner. So... cute. It gets a 2/5.
