I agree with two other reviews that 1 - Byron is a major jerk; and 2 - this was better than the first.
This movie isn't the usual Hallmark Saturday night, but then I don't think it is a Hallmark production. I don't recognize the studios. And this series premiered in Canada earlier this year.
There are some similarities to the Wedding Veil series in the aspect of female friendships supporting one another in love. This series has the four girls who actually formed the club in college.
The idea of a woman pining after her ex, Byron, is common. However that history produces a twist before the climax. Byron's rival love interest is also handled a little differently than the usual.
Byron is a total jerk. I was absolutely floored when he took a strawberry out of Sydney's funnel cake without asking or being invited. The way he treated both women was bad and bordered on mean. Despite the fact I thought this part of him was overplayed, Jeremy Walmsley did play the part he was given well. (Not as sure how well he portrayed the running at the end of the race.) As irritated as I was with his character, Byron definitely created tension in the story.
Similarly Lily Gao. I thought Sydney was past pathetic and I would have liked to see that aspect toned down a little at least regarding her whining. But I think that was the part Gao was given. She was especially good with Jesse Hutch and she radiated happiness.
Like the Wedding Veil series, I think it is strange how far the friends go to support the current central character. They drop everything and travel to stay with her for apparently a week. During the day, when they aren't stalking one of the other characters, they apparently sit around doing nothing (drinking wine?). In this movie they really got involved in meddling with Sydney's love life.
I think this movie is probably slightly better than my rating which is influenced by personal dislikes more than quality of the story.
