Signs (2002)

In M. Night Shyamalan's scary horror film about alien visitation:

• the awesome opening scene of ex-Bucks County Pennsylvania "father" and emotionally-wounded widower Rev. Graham Hess (Mel Gibson) awakening to find his two dazed children Morgan and Bo (Rory Culkin and Abigail Breslin) in their cornfield looking at huge crop circles, with Morgan's thought: "I think God did it"
• the scene around the dinner table with Graham's anger about prayer ("I am not wasting one more minute of my life on prayer") followed by the family's hug
• Graham's speech about two kinds of reactions to an experience: ("See what you have to ask yourself is what kind of person are you? Are you the kind that sees signs, sees miracles? Or do you believe that people just get lucky?")
• the scene of CNN news footage from a Brazilian children's birthday party, showing home video footage of a brief shot of a green alien walking past an alley, with horrified younger brother Merrill Hess' (Joaquin Phoenix) urgent warning shouted at the TV to the birthday party children: "Move children!! Vaminos!!"
• the scene of the blocked kitchen pantry in neighbor Ray Reddy's (director Shyamalan) house, where Graham discovered a trapped giant alien - when he bent down, knelt, and tried to look under the pantry door (using the reflection of a shiny, large butcher knife). On a second attempt, the alien grabbed at him. He used the knife to cut off two protruding fingers on the alien's clawed hand reaching out from the underside of the closed door - causing the trapped creature to let out a high-pitched, blood-curdling scream.
• Bo's calmly-delivered line in the dark basement: "There's a monster outside my room, can I have a glass of water?"
• the final climax when a tall greenish, gas-expelling alien broke into the Hess household and put the weak and asthmatic Morgan at risk - but was killed by dousings with glasses of water (acting like acid on the alien), and swings of Merrill's baseball bat! ("Swing away, Merrill. Merrill... swing away")
