You Can Count On Me (2000): A single mother’s life is thrown into turmoil after her struggling, rarely-seen younger brother returns to town.
This is such a superb movie on every level. Laura Linney was nominated for an Oscar for it, as was the screenwriter, and it is one of the best performances I have ever seen by Mark Ruffalo. I found it to give commentary, in a very subtle way, to the fact that sometimes brothers and sisters can be the best life partners. Not even in a sexual way, but just how they can be there for each other through thick and thin like no one else.
Even though in the film the brother (Terry) has not visited his sister (Sammy) much, they are able to pick up their rhythm again just like when they were kids. In the movie, both siblings seem to be finding love with the wrong people, but it seems like each other are who they are really meant to be with.
You can just imagine how many people have watched the film and said “too bad she couldn’t find someone like her brother.” Especially to her son Rudy (played by an adorable young Rory Culkin), he makes a perfect father.
Even though in the end the siblings go back to their separate lives, this is the reality with so many brothers and sisters and that truth is a real testament of the film.
