Roger Ebert:Review: Signs.In:rogerebert.com.Abgerufen am 28.Dezember 2008(englisch):„M. Night Shyamalan’s Signs is the work of a born filmmaker, able to summon apprehension out of thin air. When it is over, we think not how little has been decided, but how much has been experienced […] At the end of the film, I had to smile, recognizing how Shyamalan has essentially ditched a payoff. He knows, as we all sense, that payoffs have grown boring.“
