GO TO THIS MOVIE!! Buy Tix on line- the show is sold out by the time you get there. Get your tix, go in the theatre and save seats, then go do any other things you need to do before the movie starts- then settle in for a fantastic entertainment experience. What a mind that Cameron has to create such a world. I found the 3-d effects not over done at all- no problem with motion sickness here. If you have any concerns- sit in the back row- I did and the movie was still very immediate feeling. Go and enjoy!
