Continuity mistake: In the scene where Merrill, Graham and the kids are returning home from town, and Morgan is holding his baby monitor to listen to the aliens, his fingernails are very long. When he gets out and climbs on top of the car to get a better listen, his fingernails are very short. (00:29:55 - 00:32:15)
Signs (2002)
Ending / spoiler
Directed by: M. Night Shyamalan
Starring: Mel Gibson, Joaquin Phoenix, Abigail Breslin, Rory Culkin
The aliens are unable to break into the cellar. Hearing on the radio that the space ships have left Earth, the family emerges. The invaders are seemingly gone, but when Graham and Merrill go into the living room, they are confronted by a stranded alien. It is carrying Morgan and about to shoot deadly gas into his face. Suddenly recalling his wife’s dying words, Graham tells Merrill, a failed semi-pro baseball player, to "swing away." Merrill grabs his old bat from the wall bracket. The threatened alien releases the gas and drops Morgan to the floor. Graham grabs Morgan, who’s having an asthma attack, and rushes outside to give him a life-saving injection. Meanwhile, Merrill attacks the alien with the bat, and after a fierce struggle, kills it. Morgan survives, his asthma preventing him from breathing the poisonous vapor. Graham believes this was God’s way of saving his son. His faith restored, he returns to the pulpit.
Graham Hess: Everybody in this family needs to just calm down and eat some fruit or something.
Trivia: Ray Reddy (the man who accidentally killed Graham's wife), is the writer/director/producer of the film, M. Night Shyamalan.
Question: Do the individual aliens have cloaking abilities? It seemed at that the dogs were reacting to something that the people could not see. Were they smelling cloaked aliens? Were they going crazy to protect their human owners and that was misinterpreted as an attack on the people? I thought they are walking around at least invisible at times to do their work without detection. I may be wrong on that.

Answer: The aliens were not cloaked, not invisible. They had a chameleon-like ability to change their appearance to match their background. Recall the alien's fingers turning plaid when he held the boy. They seem to be that green color when not camouflaged. The better senses of the dogs did allow them to detect the aliens. However, one of the effects of alien presence noted in the movie was a change in personality; that is what happened to the dogs.
