I would prefer that they write great characters and then hire the best actor or actress to bring the character to life. '"A"-List actors' aren't necessarily the best actors, just actors who can command higher salaries. You also presume that Star Trek (2009) will be "drek". I prefer to wait and see the finished film before making a comment about the casting choices.
Exactly. I'd prefer the best person for the role over the most famous person who wants the role any day.
