These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Big Lipped Alligator Moment: The pool scene. It breaks the flow of the movie, accomplishes little narratively, is very fantastical in a cinematographic sense while the rest of the movie is fairly realistic, and basically exists to fill screen time.
Crowning Moment of Heartwarming: At the very end, when Bliss' mom reads her daughter's Bluebonnet Ball speech. It turns out that Bliss names her mom as the person she admires the most.
Les Yay: Eva Destruction and Rosa Sparks. Also, a little between Maggie and Bliss.
Personally, I find that there's no "straight" way to interpret this film. It's tailored to the female-friendly eye (particularly obvious in that the film is a basically a story about a girl finding her place mainly aimed for female viewers, and is just about the sexiest sport they could have chosen), the point of the main character's relationship is essentially "boyfriends actually stink so stick with your ladies". If you listen to Eva and Rosa's conversation, they flirt with "there's some stuff I'm pretty sure I could teach you". How does the final encounter between Bliss and Iron Maven go? Maven (someone who has been relatively antagonistic towards Bliss the whole film) compliments one of Bliss' moves and Bliss responds that she'll teach her sometime. If teaching someone something is this movie's gay code, that would definitely shed an interesting light on many interactions between Bliss and Maven, especially when the food-fight scene ends with the two of them rolling around on the floor, Maven laughing as she's pinning Bliss (Foe Yay anybody?). Mileage may vary, but I really feel that this film is intended more for the gay audience than most people realize. Which is great.
Romantic Plot Tumor: Bliss' romance with Oliver has very little bearing on the rest of the plot—it gives her a reason to ditch Pash, and a reason to reconcile with her mom, and that's about it. Though it does provide a neat deconstruction of the Satellite Love Interest.
