I'll give it 3 stars because it was great to see a movie which isn't just about identity politics plus some of the special effects were pretty good - however some of the crowd scenes seemed unconvincing.
As much as the effects were generally good, the cut scenes between darkened caves, hidden faces and the bright desert ended up being too garish and unappealing.
Plot line? Seemed like there were gaps in the continuity, poor editing? At certain points it seemed to jump ahead in time with no warning. Also the movie became quite boring because nothing was really happening.
In terms of acting, Rebecca Ferguson was a highlight.
Overall 3 stars but really it was the boredom factor, towards the end I was really anticipating it being over so I could go home.
I'm glad I seen it but I couldn't imagine myself doing it again.
