Movies have the ability to flourish over a long period of time.
For example, there is a young Michael B. Jordan (Creed, Fruitvale Station), a rising star in cinema in one of his earliest films. You also have the guy who played Apollo Creed's illegitimate son and Neo from The Matrix in the same movie. Put two and two together and over time, a film can flourish. This movie is who Keanu Reeves is in real life. He gives back to the community and takes pride in being a good person and because of his reputation as a good person, this film will gain further popularity in years to come. Moreover, as careers flourish of any artists, their earlier works can flourish with them despite not being popular at the time of the release.
The logline on Netflix states:
"A gambler agrees to coach a Little League baseball team from a notorious Chicago housing project if a friend will lend him money to square his debts."
Keanu Reeves' character, O'Neill, is reluctant at first about his new responsibility but as we see him change, he learns of what huge impact he has on these kids. The story doesn't even show how great of a coach he is. In fact, he is a terrible coach. But, the point is that when kids have someone to look up to they will perform their absolute best. That is why it is amazing to see these kids win in this story despite what their struggles are growing up on the south side. The movie shows that kids can overcome anything if they have an "outlet" to escape and a great role model that inspires them.
