If you are under 12, you might find this movie exciting, but just because the movie has digitally animated characters doesn't make it good- just a glorified cartoon. Personally, I found the 1970's/80's special effects much more realistic looking (Remember some of the characters from the first three Star Wars movies?) The plot of Avatar is nothing new- a bunch of greedy/irresponsible scientists and military planning to invade/exploit a harmless bunch of natives.

The main female avatar was especially annoying- whiny, unstable and hostile- but hey, isn't how most female characters are (unfortunately) portrayed on TV and in movies these days? If you saw Avatar because it was 3D, the effects were pitiful compared to those (albeit very gory effects) of My Bloody Valentine or The Final Destination.
