I have seen Avatar twice now; once in 3D, and once in IMAX 3D. To tell the truth, I did not notice too much of a difference between the two besides the larger IMAX screen. However, I was unable to truly enjoy the screen because the show was sold out, and I had to sit in the second row. On to the movie - Avatar is amazing. I would highly recommend it if you are unsure of going. While the controversial messages of the movie are clear, they do not come across as preachy. The visual effects are stunning; with the 3D glasses on I truly felt like I was in the film. The story is creative and ends well. Go see this movie!! (In 3D)
