I'd never force this 3D film on my audience. It definitely has it's problems. But, it's like a rollercoaster ride at an amusement park. Some people will heave, and others will be so thrilled, that they'll get right back on and ride it again!
I have to agree with Ron on most all of his criticisms about the films plot, character development, the condition of the elements used, and the eyestrain, or even headaches that it may cause some viewers because of the extreme (and perhaps even careless) use of 3D by the filmmakers.
