I had never heard of this ancient city, which is a real place, an archaeological site in what is now Pakistan. Since the movie is about a real place about which little is known, there’s a disclaimer reminding viewers that the movie makers made use of artistic license—they’re just telling an interesting story about the place, not trying to tell the true history of it.
The sets and costumes were interesting, but the plot seemed forced. The country-boy hero has a secret destiny, goes off to the city, falls in love with the princess/priestess, discovers his true identity, saves the day, blah blah blah. There was a lot of telling rather than showing.
