OK so this wasn't the best bio movie. They crammed 50 years into 2 hours so there is little detail or depth therefor, if you didn't really grow up in that time period, knowing who Olivia Newton-John was, this movie won't mean much or be very entertaining... you might even get a bit lost. For fans or people from that generation, we know some of the actors/people she dated, the movies, songs, and some of the events so we can fill in the blanks. All the acting was pretty mediocre. I know other reviewers especially trashed actress Delta Goodrem but I thought her acting and singing were descent enough, and she is an Australian singer and actress so she had the authentic accent and a good voice, even though she's no Olivia Newton-John. So, not the best but might be entertaining enough for a fan or a dull afternoon, In My Humble Opinion. 5.5 stars. Feb 2019.
