Good flick, well written, interesting characters and good action. Holmes is acted superbly by Downey, and he and Watson make a believable team. Best parts are Holmes' kung fu moves, as well as his constant ramblings of his lunatic attention to detail.
Although I'm easily amused with the action genre, I still see the cheeseball lines and in some instances, poor CGI in a few scenes that make you lift an eyebrow. But overall Wolverine is a great movie, and will satisfy most fans of the comic books. The action is fast and furious, and the emotions and adrenaline run high in almost every scene, especially with Wolverine's brother, acted very well by Liev Schreiber. I give it a B+.
