Planes, Trains, and Automobiles
While I don't know if this exactly qualifies as a road movie, this movie came to mind immediately. I first watched this movie with my dad because he wanted to share one of his favorite movies with my siblings and I. I fell in love with the humor and sense of adventure portrayed in the film. The constant setbacks and mishaps experienced by the two main characters in their quest to make it home for Christmas made me cry with laughter the first time I watched this movie, and the heartwarming ending played into my love of 'happily ever after' endings.
