I only saw Blue Velvet and Wild At Heart, and they're masterpieces. Although some Lynch's movies are total crap, for example Mulholland Drive.All of Lynch's movies are disturbing. I also hate them all - especially Lost Highway.
Well, movies that specially touched me were Forrest Gump, American Beauty and Bridges of Madison County.
There are lots of other ones which lured tears out of my eyes, but if someone asked, I'd mention these three immediately.
