Okay, so the plotline is very standard, really. Avatar doesn't push the envelope with that. What it DOES do magnificently though the world, both graphically and in terms of how it is set up. You REALLY feel for the Na'vi people by the end of the movie. I would highly recommend this film, and if you do see it, it is WORTH it to spend the extra money for IMAX. I've seen it both in IMAX and RealD, and it's also worth the extra buck for the IMAX. Just make sure you get good seats!
