Addictive and a whole lot of fun . . .

Modern love storylines often suffer from a lot of unrealistic danger, whereas historical/fantasy storylines often suffer from outdated romance ideals. So, what if you combine them?

This drama concept isn't new, but it's very well done. The leads have great chemistry, the plot is fast moving, there's lots of protectiveness/rescuing/sacrificing scenes blended with a lot of humor. As with all great dramas, I was reluctant to leave the characters and universe behind.

Music was competent, and while endearing, I'm not sure I'd ever be tempted to rewatch.

I grade on other criteria as well:
Complex Themes - 5
The clumsy (though well-intended) theme is exploring equality in gender roles for both society and relationships. The better executed themes are around learning to be your authentic self and trusting others, as well as what makes a kind and generous person.
Character Growth - 7.5
Both main leads grow and change as a result of the relationship and are transformed as people by the change from a fake relationship to a real one. The rest of the characters are fairly fixed, and second sister's character development is sudden and clumsy.
Complex Female Characters - 8
There's lots of relationships between women, women in leadership roles, and women with complex personalities. The city leader was a great blend of calculating and cruel vs. protective and generous
Production - 7
It did not get in the way. Limited sets and shooting outdoors, everything was shot fairly straight on, costuming was lower budget but in good taste.
