Close Encounters of the Third Kind — IQ Score 165/200

Spielberg's 1977 alien-arrival film whose structural commitment — that contact is genuine collaborative communication rather than invasion — defined the optimistic-first-contact register Hollywood SF largely abandoned after Independence Day. Richard Dreyfuss's Roy Neary obsessively building a Devils Tower scale model from interior compulsion is rare protagonist-as-cognitively-altered work.

The five-note John Williams motif is genuine score-as-narrative-material.
