Parents need to know that Boss Level is an action/sci-fi movie about Roy Pulver (Frank Grillo), who's stuck in a time loop, repeating the same day as he tries to survive relentless killers, rescue his wife and son, and save the world. The violence is gleefully outrageous, graphic, and excessive, with lots of guns and shooting, characters being shot and killed (including by self-inflicted gunshots, with the knowledge that it's not permanent), high-powered weapons, swords, blades, beheadings, bloody wounds, explosions, car chases/crashes, an arrow through a chest, and more. Language is also strong, with many uses of "f--k," plus "motherf----r," "s--t," "son of a bitch," and more. Roy picks up a woman in a bar, and they flirt and kiss before he lifts her up and carries her to bed. He also drinks a lot and gets drunk in one sequence. Cigar smoking is also seen. The movie stumbles a bit over its own ideas at the end, but it's exhilarating, clever, and even touching.
