Stealth kicks off by showing off its most high quality element: its impressive visual effects. It uses CGI to create some awesome aviation sequences interspersed with plenty of explosions and well shot action. Soon after it shows just what its fatal flaws are.
Stealth borrows the story element from 2001: A Space Odyssey which relates to technology developing a mind of its own, but in Stealth that is senseless. Its used simply as a an excuse for lazy writing and isn't explored beyond an iench of the concept. It's like Stealth is a film that attempts to use that concept as a front for action and show the idea to the younger audiences that would appreciate the action, but with no intelligence behind it just collapses under a lack of structure and the way it can't handle its theme of Artificial Intelligence.
The AI is ridiculous as well because as it develops it learns to swear which is just pathetic. Its an example of the flawed script which is full of ridiculous dialogue which is obviously generic dialogue which parodies any government themed action film ever made without interesting any clever elements whatsoever into it Its all thoroughly weak throughout all of Stealth. Some of the worst lines are forced upon Jamie Foxx whose character is so weak despite his best efforts that when he dies in a poorly shot and shoddily edited death scene, the only thing viewers will feel is annoyance. And since Jessica Biel can't shut up with her lines in the scene where she ejects from her stealth jet, she just keeps throwing out more and more poorly conceived dialogue which reminds us the quality of the script and her shortcomings as an actress. For a character meant to be a United States Navy Lieutenant she conveys more a feel of a damsel in distress, and that is the last thing a film like this needs. Josh Lucas is the only one that comes out half decent even after the film has already dealt its damage to him.
Stealth is an example of a big-budget film which is excessively reliant on nothing more than CGI during all its sequences that are meant to highlight the better qualities of the film, but even at times the CGI comes off rather poor. Its good in the aviation sequences but bad predominantly the rest of the time, and it doesn't feel genuine because there is an overkill of visual effects in Stealth. It lacks the touch that Top Gun had, even though that in itself wasn't such a great film.
Stealth shows that director Rob Cohen knows less about being a good film director than he does about making use of visual effects, so Stealth ends up being an overblown and loud video game-ish experience, and not in a good way whatsoever. While its action may please the junkies, its overkill and lack of intelligence makes it $135 million letdown.
