If I hadn't been required to see this film (long story), I would not have. While the production techniques and sound recording were well-executed, the movie itself was pointless, much like any biography of a 16 year old would be. It was mainly sweetness and light, a "Wow! This could happen to you if you had talent, too" type of love fest.
Bieber didn't start the teen idol phenomenon, and he won't end it. He's had fabulous luck. So what. That alone doesn't require 3-D memorialization.
If you want to see a movie about overcoming obstacles to reach your goal, go see "The King's Speech". Oh, wait - King George didn't have floppy hair.
A fine movie overall. I was slightly confused by the fact that the location shots were obviously Chicago (Lower Wacker Drive, anyone?) I had no enthusiasm for the role of Rachel, and apparently neither did the writers. Lovely explosions and stuntwork, and excellent makeup. The IMAX version has magnificent sound. A very good way to spend 2 1/2 hours.
