Our review:
Parents say (45 ):
Kids say (104 ):

KNOWING wants to be a lot of things, but logical isn't one of them. From early in the movie when John lectures his M.I.T. students about randomism vs. determinism (unsubtly setting the stage for what's to come and also sounding like he's talking to a seventh grade class) to the final moments when Earth's very survival is at stake, style and action take precedence over coherence.

The characters never behave in a rational way, instead serving only to move the story from one harrowing event to another. In its desire to cover such major issues as humankind's frailty in the face of nature, religion, parenting, and even a glimmer of hope for the future, the film loses its way amid showy special effects, thinly drawn characters, and lack of plausibility. Dark City, an early Alex Proyas movie, was far more successful at giving life to the science-fiction genre.

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
