X-Men Origins: Wolverine is essentially a prequel to the Wolverine movies, and is essentially a movie to describe how the Wolverine became the Wolverine. This movie involves Stryker, the man who made the Wolverine's claws metal, because they were originally not this way. However, the Wolverine's story is very dark and so is this movie. This movie is somewhat twisted, and the beginning is very depressing and painful to watch. 

 But this movie does involve other characters, like Deadpool, and the Wolverine's brother, which definitely makes this movie more exciting to watch. This movie definitely has some great scenes, and great visual effects, and is a fun movie to watch, but the beginning might be too dark for some.
