Who's saying she's overrated? She dosen't get nearly as much respect as other X-Women. She's a complex character with an interesting backstory. For some reason, though, the writers use her as a trophy for what ever male character they like - Gambit, Magneto, Deadpool, ect. I wish Marvel would start focusing more on her as an individual and not a prize to be won.

Rogue should be played by an anctress in her early to mid twenties, especially if they introduce her as a member of the Brotherhood of Mutants. I can see Millie Bobby Brown or Kiernan Shipka playing Rogue.
