Krull, Gremlins, Cloak & Dagger, and most definatly WarGames ( i always thought broderick was cool as shit and i wanted to hack into shit like him)
then these are obligatory...Star Wars, Empire Strikes Back, and Return of the Jedi (NO SPECIAL EDITION CRAP)
and finally, all the "hip" teen movies : Weird Science, Breakfast Club, Sixteen Candles, Better Off Dead, etc.
but last but certainly not least my fav movie ever: BIG TROUBLE IN LITTLE CHINA ROCK ON!!!!!!
