The only thing about this movie worth watching...

Rating: Null/10 (11 November 2004)

...were the special effects. The rest was plain, unadulterated ka-ka. Transparent characters. Idiotic plotting. Predictable who-lives and who-dies assignments. Faulty science. Not that I'm a stickler for pristine science, in general - movies invite suspension of belief all the time. But in this case, I think the faulty science mixed in with everything else that's wrong with this movie actually did a severe DIS-service to the very cause they were trying to promote - waking up to what we're doing to the environment and "fixing" it before it's too late.
But again I say - the special effects were AWESOME! Worth the price of admission/rental.
