In the Pixar Movie Up, is Carl Fredricksen's decision to go to Paradise Falls a metaphor that indicates the intention to commit suicide?
I know that after all this movie is a comedy-drama adventure and some details of the story are omitted, as in many movies of the same genre, but thinking in a detached manner, I noticed some points that make me think to suicide.
The biggest one is that Carl can't get food easily in Paradise Falls, he is old and lame and in the falls habitat is really hard to get food.
The choice of Carl to leave the city in that way with the intention to go to the Paradise Falls makes me think to the famous phrase heard in a lot of shows (movies, TV shows, etc): "I prefer to die rather than to go to a hospice".
So, thinking as an adult, not as a kid, does Carl Fredricksen decide to commit suicide?
