The graphics in this game are very standard for a Wii port of a movie-based game. In other words, they're not all that great. Animations are stilted and awkward, and there's a whole lot of clipping. This effectively breaks whatever sense of immersion the developers were going for. However, the character models for Wolverine and Victor Creed (aka Sabretooth) are actually quite decent. To be honest, I have not been following the movie at all; the only thing I knew about it before I played the game was that Hugh Jackman was going to reprise the role of Wolverine. That being said, I was able to recognize Liev Schrieber's face in this game, and sure enough, he portrays Sabretooth in the film. That, unlike the rest of the visual presentation, is impressive.
The game sounds decent, but from a technical standpoint, it is seriously flawed. Sometimes the music track will completely drop. Occasionally, the sound will completely bug out, and you'll hear a number of overlapping screeches. Nobody ever wants to hear that. The voice acting is passable, but it's nowhere near the same level of games like The Darkness. The same applies to the rest of the sound design.
