Last night in Soho. I thought this was going to be decent film to watch due to the trailer. Plot could have been less linear, ending was meh.
We went to watch King Richard, based on a true story of how Richard Williams coached two of his daughters to be Pro tennis players - Venus and Serena Williams.
We both very much enjoyed the film, Will Smith playing his role particularly well.
Perhaps even more enjoyable as the story was based on real events. The commitment and "focus" of Richard, along with his wife, was completely dedicated to the success of his daughters, but not at the cost of excluding other aspects of their development. Overall 9/10.
I think you might be taking the dramatisation of their lives and upbringing without as much salt as you should be. Like all these stories its been "embellished" and perhaps paints a different picture to the reality. I'm sure if you ask other people around at the time they will tell a slightly different tale.
"King Richard" was the executive producer on the film so will have had a fair say in what made the cut and what didn't and how things should be portrayed. The stories I have heard paint him to be a man with a god complex who very much did neglect many aspects of raising normal healthy children in his pursuit of glory.
