I felt there are many positive messages in this movie. Hearts soften, personal walls are torn down, characters find new strength and purpose, and friends encourage and support each other.
I read several negative reviews about the fact that one of the girls loses her virginity, which is true. It is not shown, (other than a few seconds of passionate kissing, both characters fully-clothed) but you understand that it happened. I feel it is important to point out that the occurrence is not glorified or glamorized. If it had been, I would have negative things to say. However, I felt it was handled well and it was made clear to the viewers - and the girl's peers - that she was heading down a dangerous path with her bold flirtations. (*possible spoilers*) The young man she was flirting with even realized she was coming on too strong at times and walked away. When they both did get carried away, it was clear that it was a mistake, not to just the viewers, but to the two characters, as well. In fact, the girl is shown feeling empty after it happened. I felt that the whole thing opened up the possibility for some meaningful conversation and teaching moments between parents and their teens about the consequences of our actions and how attractions can be carried too far.
Some reviewers also mention a second girl losing her virginity, but if that's the case, it's not obvious. She and a young man are alone on a boat at night, but there is nothing more than a few seconds of kissing at one point (again, they are also fully clothed). It's left up to the viewer to decide if anything more happened between them.
As far as any other sensuality goes, there are a couple of scenes in which you see some of the girls in their underwear but in the context of changing pants and going swimming. I could have done without it, but it was not done in a sensual way. You also see a young man with his shirt off in the context of swimming. Later, you see drawings of him with his shirt off and I was more uncomfortable with the drawings than seeing him swimming with no shirt on.
One thing I had a little difficulty with (*possible spoiler*) was seeing an engaged couple living together like a happy family before they were married. I realize some people don't see that as an issue, so it depends on the viewer's personal point of view, but I felt that portraying a couple living together before they were married as being a positive - or normal - thing sent a less desirable message than the portrayal of young people getting carried away, making a mistake and feeling remorse.
There is some smoking, done by adult employees on their work break, not by any main character. There is also brief drinking and evidence of drinking by the soccer coaches after work hours. No one got drunk. Three young people sneak out to go to a club, but they do not drink.
The only thing that prevented me from giving this movie one more star is the unnecessary profanity. Granted, it is more mild than many other movies, but I felt that it was not necessary and was a bit excessive.
I enjoyed this film. I love how diverse each of the girls are. I think teenage girls could relate to at least one of the four main characters with their flaws and their personal and family struggles. The film deals with divorce and loss of loved ones and portrays friends coming together, encouraging each other to express their grief, helping each other get through their challenges. Overall, it left me feeling uplifted. I've seen it twice so far and would watch it again.
