2. Harold and Maude
Harold and Maude came out in 1917, and it done something that had never been done before and since. This movie talks about a young man (very young) who fell in love with 79 years-old woman. Consider the era that this move came out, the audience didn’t take it kindly.
However, years went by and the era changed, and the attitudes towards Harold and Maude finally changed and many finally acknowledge the movie as it supposed to be, a love story.
