James Berardinelli: "Like The Sixth Sense and Unbreakable,
Signs is not easily pigeonholed into a single genre. It gleefully crosses boundaries and defies classification. In many ways, it is Shyamalan's most accomplished film to date. Unlike The Sixth Sense, it doesn't rely on bamboozling the audience. And, irrespective of its flaws, Signs is more satisfying than Unbreakable. Despite the financial success of his two previous outings (combined, nearly $1 billion worldwide), no one is yet ready to reserve a place in the director's hall of fame for
Shyamalan, but, based on the evidence available in Signs, he is maturing nicely."
