Exactly....and that was my whole point with Avatar. Just because you throw money at it doesn't make it a good film. Take away all the money spent on special effects and that instantly becomes a horrible film. It's not an original story, it's been done many times before. All they did was use a half billion dollars worth of special effects.
It's a shame that so many original scripts get overlooked just so some studio can remake some film from 20 years ago
