Every movie is what makes Will who he is today. Take away Wild Wild West, and you're taking away that certain experience he had with Wild Wild West. Take away a certain album he's made, and he wouldn't have learned from that experience. Will knows how 2 learn from his mistakes, but I think at the end of the day, there's nothing he shouldn't have done. Everything he's done is what forms the knowledgable Will Smith we see today. He learns something new with every movie.
