I was blown away by the cinematic tech breaktrhough that Cameron has acheived. The future possiblilites will be astounding and (hopefully) not limited to si-fi adventure. The naturalness is what stuck me the most. Without the new tech (and also amazing CGI) I would have rated the film a 4-star...(I found the story line predictable as soon as the romance and evil military roles were established). Mike Todd may not have transformed film with his smell-o-vision, but Cameron has with his 3-D and he deserves the boxoffice benefits of the incedible effort and risks taken.
