I thought the movie played true to the book. I still wish the special effects of Edward "glittering" in the sun was better. I thought the acting was much better than the original as well.
The 3-D effects are great and this movie was fun for the whole family. I was disappointed that it was not available in more theaters, but it was definitely fun. It gives a little bit of history of the lunar landing too with an appearance by Aldrin.
