Very well made technically, with the exception of a few shaky composite shots. Good balance of action and narrative. One big fault: more senseless killing of likeable characters than in any previous X men film. Wolverine himself was also more vengeful, to the point of becoming downright bloodthirsty. The memory loss in the end was a bit of a convenient way to rectify this disconnect with the other movies. The film could have progressed just fine without the senseless violence. Can't see why so many producers and writers feel it necessary.
