Engaging and with a very great plot!  What seems like an ordinary and dull hospital stay for an elderly man became a test for his character and moral values.  Turns out, the other old man with full access to the window made him believe and imagine a colorful park and environment where there was none.  However, the unwillingness of that old man to share the window with him made him decide not to help him during a cough attack.  There are plenty of lessons that viewers can pluck from the animated film, and in the case of the elderly man who didn't push the help button, he will surely be forever burdened with his conscience.  Great visuals, this is definitely a must-watch!
