The acting was believable for the royals. A viewer gets a sense that the 'royals' have had special training and have grown up in a different world, but NOT over the top different.
The main actress does a very good job with her role, with 2 different faces. Many movies with a princess, the actress does not in any way shape or form give off anything that implies a lifetime of specialty training and decorum. Those kind of movies are real cop out. This movie does a good job comparing the two worlds, without vilifying either one.
There is no proverbial evil antagonist (almost always Caucasian male sometimes female) for a change. I have heard from people in the movie industry that it is hard for script writers to develop an engaging movie w/o one. It was a real treat and relief to just have decent people who mean well even if their views were different as the primary movie characters.
A very nice and engaging low budget movie
