To put it simple: boring and mediocre movie. Luckily, it is short enough and you will not waste too much time.
It is about mentally unstable man Mark Ruffalo, who lives in Boston and suffers paroxisms of anger. His wife with two daughters moved away from him and started to live in a poor neighbourhood. Then, his wife decided to get a degree in busyness and decided to attend univercity in New York. So she left daughters to this ill man and visit then from time to time.
The entire plot is based uppon the challenges of rising kids. He was yelling on thenm drove them to school and cooked them meals.
Looks like some society of bipolar disodered people decided to raise the awareness amond public and ordered a movie that shows that these peoples are also humans with thaeir weak and strong sides.
