That is the danger of attempting to remake an American classic. Push too hard, and the message becomes cumbersome. Attempt to over-stylize, and the message becomes lost all together.
I’m always wary when watching the third installment (the three-quil, if you will) of a movie series. Think Godfather 3, Terminator 3: Rise of the Machines, Spiderman 3, or the Matrix Revolutions. Then again, there has been a reverse in the trend recently with The Dark Knight Rises, and now, with Ironman 3.
