WarGames
Plot:

WarGames is about David Lightman, a teenage hacker who accidentally hacks into the North American Aerospace Defense Command (NORAD) computer system in an attempt to access the computer system of a game company. He believes that he has accessed the computer system of the game company, and tries to play the game "Global Thermonuclear War." NORAD thinks that the program that David started is real, and that the Soviet Union is attacking them. David realizes his mistake, and with the help of his friend Jennifer Mack, and Professor Falken, who designed the NORAD computer system. NORAD stops the counter attack, but the NORAD defense computer, War Operations Plan Response (WOPR), attempts to gain access to the launch code and launch the counter-attack anyways. David tells WOPR to play a game of tic-tac-toe against itself. It finds that it will never win, and the game will always tie, and finds that the same is true of a nuclear war. Learning this, WOPR calls off the attack.
Review:

Overall,
WarGames is a great movie, despite some plot holes and bad acting. Specifically, the acting didn't seem very realistic, and the actors didn't seem to be really into the role of their characters. The plot of the movie relies on some coincidences to set up the story, but beyond that is great. The movie is great aside form some bad acting and plot holes. I give it 3.5/5 stars.
