Parents need to know that Thunder Force is about childhood friends Lydia and Emily, who reunite as superpowered adults (Melissa McCarthy and Octavia Spencer) to fight off villains. It boasts positive, diverse superhero representations but also has quite a bit of action violence and salty language. Lydia and Emily demonstrate cunning, courage, and teamwork, and Emily and her daughter are brilliant Black scientists whose inventions will save Chicago. The women get involved in brawls and knock-down fights, many of which include violence in the form of explosions, falls, tasers, and gun shots. People get squeezed to death and electrocuted and fall out of skyscrapers. One of the villains, Laser (Pom Klementieff), could frighten some viewers with her intensity and professed love of killing, and another's eyes turn a menacing red when he gets angry. Lydia flirts with a villain known as The Crab (Jason Bateman), imagines dancing with him, goes out for a romantic date, and goes home with him, where they start undressing each other. Language includes several variations on "s--t" and "ass," as well as "bitch," "damn," "suck," "hell," anatomical terms like "balls," "butt," and "tatas," and taunts like "morons," "loser," "psycho," "idiot," "dork," "wack job," and "nerd." A character mouths "What the f," and another stops at "mother--." Ultimately, the movie offers the message that superheroes can come in all shapes, sizes, educational levels, and genders -- and that honesty and integrity win out over lying, cheating, and scaring or hurting people.
