Better than its rating Yes, it's full of movie clichés. Yes, the acting is "eh" at times. Yes, apparently, it's a somewhat unrealistic portrayal of how swim meets work.
However, barring all that, it offers an inspirational lesson, and is based on a true story, so I can't really bear witness as to what's realistic and what isn't. What is true is this: in 1974 Jim Ellis helped save a rec center in a depressed neighborhood in Philadelphia and created a swimming program that, in real life, proves the old clichés.
From Wikipedia: Ellis' protégés include Michael Norment, the first black swimmer on the U.S. national team. His program at the Marcus Foster pool has sent swimmers to the swimming trials for every U.S. Olympic team since 1992.
I don't understand the people who gave it one star. There are so many more movies that deserve much worse than this. If it's on cable, watch it for a little. You won't be disappointed.
