We love old English period piece media (e.g. books, movies), and thought for sure we'd love The Other Boleyn Girl. Other things in the movie's favor: Actors we like (Natalie Portman, Scarlett Johansson, Jim Sturgess), A cool movie poster (Never an actual sign of a good/bad movie), Some decent reviews, and our general enjoyment of cheesy love stories. But despite all of these factors, we really did not like the movie, it was that bad.
The Other Boleyn Girl follows the lives of the two Boleyn girls, who historically became mistress and queen to Henry VIII of England. Mary is married young, and catches the king's eye, becoming his mistress for many years. All she desires is to love and be loved by a man, and a simple life in the country. Anne is young and ambitious, and ends up winning the king's heart while her sister is on bed-rest, pregnant with the king's son. The movie is full of sex, sex, sex, conniving, beguiling, and overall treachery.
Quick vote: Don't see this movie. It's really that bad.
