The CGI in Avatar is pretty great, the one sequence that doesn't work is the first completely day time sequence on Pandora, though even that picks up about halfway through. The problem, visually, with the film, is that is does not use enough wideshots.
Anyhow, my Pet Peeves are friends who make you stand in line for them while they look at a magazine. There was a Seventeen Prom Magazine that I'm pretty sure had Selena on the cover. Now how will I know what my perfect dress will look like?
