The movie has some intense scenes, but they all end in a comedic way, except the ending scene. The end is very intense and serious, especially since it's very unexpected and suprising. The camera also shakes which makes the intense scene, including the movie's end, feel more realistic and dangerous.

There are some intense arguments.
A man with cancer is seen in agony; his meds are not with him.
Overall, the movie is very emotional, especially the last fifteen minutes of it.
