I have no idea what the so called professionals are thinking. This movie was awesome in everyway. Could they have got different actors for the lead roles? Maybe. After watching it a few times I think they did a great job. Rhiana was just ridiculously entertaining in this role. Bottom line this movie has everything and in my opinion easily better than Avatard. Maybe some decade they'll come out with number 2 if Cameron is not too busy floating around in his sub.
