2. There’s just something so special about a love that you can compare to two of Pixar’s greatest lover-birds. Carl and Ellie from Pixar’s Up were not only romantic partners, but best friends. The eternal power of their love is symbolized through Carl’s determination to complete the task Ellie couldn’t, essentially establishing the plot of the movie. If you can compare the love you have to these two, than you have a love definitely worth keeping.
