While I enjoyed Jaws, and am a movie fanatic, I've never felt strongly about Spielberg's movies at all. I enjoyed a few of them, but almost all of his movies are lukewarm to me--mechanical, inoffensive, unimaginative.
I read an honest book about him that praised his early work and his obvious technical talent (I don't think any director is better at using the tools of cinema; it's the purposes he puts them to that bore me), but the writer put his finger on it when he said Close Encounters was a turning point for him. After that, the childishness prevailed.
Jaws is also a great example of how a director gets all the credit for the fine work of everyone involved, from the composer, to the editor, to the multiple writers, cinematographer, actors. That's Hollywood, tho'.
To me Star Wars was one of the greatest movie experiences of my entire life.
It like the Monty Python line: and now for something completely different.
