You may have avoided this because of the title and subject matter (as I initially did). I dived into it because Laura Linney (Ozark) is the star.
Her performance is first class and the supporting cast, playing family and friends are suburb (especially her brother)
It covers all subjects - The Cancer, of course, Race, Homosexuality, Mental Health, Sexuality, Religion
It's a real 'rollercoaster' with many very funny scenes and lines, while observing a woman trying to resolve how to live the remainder of the time she has left
You WILL laugh - You will cry
