Like many, I backed this film and would love to see a Book of Mormon story brought to the big screen with broad appeal. I appreciate the director's efforts, and I know he was faced with serious obstacles in delivering this film. That being said, the script really needed some work.
I'll start with a few positives. The costume design, soundtrack, and filming location were all beautiful. That's why the three stars. The cinematography was fine, but there were too many tight shots. At times I had no idea what characters were looking at and kept hoping for a wide shot to give me context.
Unfortunately, one can't recommend a film based on music and visuals. Foremost, I first look for a compelling plot. I would've watched this had it been filmed on an iPhone and accompanied with stock music, if only the characters and plot had real substance.
The Book of Mormon explains next to nothing about this chapter in Moroni's life. But it does seem to be a sad and solitary time for Moroni. For a man who thinks he could die at any moment ("I wander whithersoever I can for the safety of mine own life" Moroni 1:3.), a romance was an odd plot to pick. I suppose it could've worked if the characters were fleshed out more. Yes, Moroni was physically alone, but why did he feel alone? What were his flaws, desires, or challenges? These things were either not clear or poorly conveyed, which leaves the character falling flat.
In short, the lackluster characters, shallow plot, some awkward dialogue, and even a couple uncomfortable scenes made me want to walk out of the theater. Maybe it was just me; the room was half full... Though I did count 3 different people checking the time during the movie.
