You may want to skip the post-credits scene as well, which features Deadpool’s sentient, yet decapitated head disturbingly smiling and telling the audience to “shhhhh”. The character Deadpool (who uses the aforementioned katanas and is not as racy as in Deadpool 1+2) is heavily experimented upon, and is scarred, has his mouth removed, and, in one extremely scary scene, has his eyes replaced with that of another mutant. Some realistic guns, katanas, plain old swords, the iconic Wolverine claws, and sharp fingernails used to slash people. In terms of scariness, Wolverine is the best there is at what he does, and what he does is not very nice. There is a couple of instances of “s***” and one (very brief) middle finger. In terms of language, expect various MCU fare, with no f bombs. Most of the scene is shot from far away, with one closeup of his butt. Wolverine loses his clothes at one point, though this scene is intended for comedy. Wolverine is in a relationship with a girl, who is never nude except for some scantly clad junk. There is surprisingly less than before in past X-Men movies (most likely due to Mystique not making an appearance). In case you can’t tell from the title, this movie features the origin of Wolverine, from his childhood to near-present day. I watched it when I was nine, so most of the stuff was kinda scary.
