biographical documentaries

I googled “girls weightlifting championship” and this was one of the first images. People complaining about the casting for the Weightlifting Fairy Kim Bok-Joo, but I think in the drama Lee Sung-Kyung passes as a weightlifter who is at the beginning of her career. She does not look like Jang Mi-Ran, the real-life weightlifter whose life was the inspiration of this drama, but it is not a biographical documentary, the actress does not have to look like her. Besides, we do not know how she looked back when she was 19-20 years old (she is in her mid 30’s now). The drama handles the body-image issues of the athletes, also the young people in general very well so far. I am also liking the “friends to lovers” progress, the OTP is so cute.
