The story arch for Rogue in The Last Stand is one of the saddest things about the film. The first two films were all about Rogue coming to terms with who she is as a mutant, and that there is a place for her being the person that she is at Xaviers. Understandably Rogue would struggle with the concept of a cure, but her eventual decision to take the cure sends a very poor message about needing to change who you are in order to fit in. For three films fans waited for Rogue to embrace her powers, and personality, to become the woman that we know and love from the comics. What we got in The Last Stand was a terrible disappointment. Imagine instead that Rogue saw some mutants with powers, either on the battlefield or even in the queues when she went to get the cure, and decided she would take their powers and use them for good. It is very understandable that if Rogue had some powers that could really help the team (like super strength and flight), she would be filled with confidence through a renewed sense of worth. Imagine Anna Paquin as Rogue flying into battle with a beautiful smile on her face.
