Which Spielberg film is your favourite?

For me it's A.I. I know it's perhaps not his finest work but it evokes certain feelings, emotions, and thoughts I never had before. It was the first time I thought about the future of technology and artificial intelligence, and as the years go on the ideas and characters portrayed become more of a near reality than pure science fiction.

It's also the first time I thought about how insignificant our time is on this planet is (pretty big thoughts for an 11 yo) and how there will be intelligent objects that can and will outlive generations. An idea that often provokes existential thoughts in my adult life.

The pure magic and emotion of the film has stuck with me and cemented it's place as my favourite Spielberg film. Which Spielberg film has had a significant impact on you making it your favourite that isn't necessarily his 'best' movie?
