No i don't think you are being narrow minded, RDJ (Robert Downey jr) is a very good actor, who can adapt to mostly any role he takes on. The first film i saw him in was also IronMan, which was a very good film, but RDJs acting skills really came through when he played Charlie Chappling in Chappling. But other roles he has taken on such as Kirk Lazarus in the film tropic thunder and Sherlock Homes really showed his acting skills can be streched.
