I too am a Spielberg child.  Forget "Gravity", which had no message other than it's dangerous to fool around in space. "Close Encounters" instead, has a true message of hope of a future peaceful encounter with extraterrestials.  Richard Dreyfus, Mellinda Dillon and the child Carey Guffey, who was only three years old when he was cast, steal the show and the viewer's hearts.  I just saw it again on TV last night, and rushed to get it (my copy ceased playing a long time ago).  This is the film to which I compare every single SF movie I watch, my standard of excelence.
