The biggest plusses for me with The Greatest Love are that it doesn't follow the standard tropes of lesbian romance and while one of the outcomes was predictable, the other was definitely not. The script and the characters reactions to tough situations was natural and believable; and the fear and anguish of the lead characters at the plot climax was palpable. The ultimate outcome was more hopeful than I expected, given the plot set-up.
I'm going to leave this review a little light on substance because I don't want to risk spoiling the experience of finding something new and different in the genre. Suffice to say, I've already watched it twice and I'll likely revisit it again. Well worth your time
