Movie is all about familial love and support, especially through tough times. Courage, perseverance, loyalty spotlighted. People rebound from mistakes by acknowledging them, changing their behavior.
Extensive pro wrestling action (including staged face smashes, chokes, throws, kicks, etc.) -- kids may need to be reminded not to copy it at home (even trained professionals get hurt executing such stunts). Also occasional real fighting, including a bar brawl in which billiard balls and cues are used as weapons.
No nudity, but the parents are very into each other. An unplanned pregnancy is part of the story. Very skimpy outfits on some of the female wrestlers -- in the ring, in training, at the pool, etc. Use of crude/sexual terms in dialogue (see "Language").
Occasional rough language, including British slang ("bloody," "wanker," "bollocks," "stiffy," etc.). Also "s--t," "crap," "ass," "c--k," "pr--k," "penis," "d--k," "ball bag," "t-ts," etc. Talk of a wrestler's genitals being exposed during a match and another getting an erection while training with a female wrestler. "Jesus Christ" and "oh my God" as exclamations.
Mention of previous drug use by parents. A coach catches a teen dealing drugs.
