This film is a modern plus classical hybrid of the Shakespearean play, Cymbeline.
After watching just a few minutes, I already wished I didn't choose this film. It's an interesting idea to put new modern scenes onto Shakespearean dialogue, but it doesn't work at all. Shakespeare fans will be appalled by the millions of anachronisms in the film, while everyone else will be put off by the archaic dialogue. A similar endeavour, "Titus" starring Anthony Hopkins already demonstrated that this hybrid doesn't work, so it's quite unfortunate that the filmmakers attempt it again. I really wonder why so many famous actors agreed to star in it. One more thing, I like Dakota Johnson in "Fifty Shades of Grey", but in this film her forehead is so overly botoxed that she could not even muster a single wrinkle even when faced with much distress. Even Milla Jovovich managed some!
I watched " Cymbeline" until the end, and trust me it did not get any better. If you don't like the first scene, then switch it off right away.
