Superman: Legacy should refrain from using Lex Luthor as its main villain. James Gunn is rebooting the Man of Steel with his Superman: Legacy story, with the film rumored to focus on a younger Clark Kent starting as a reporter at the Daily Planet. The film will be the first movie released in the new DC Universe, which Gunn spearheads alongside his DC Studios co-CEO Peter Safran. Given the importance of the movie to DC's future, Superman: Legacy has to succeed, and it is possible that the movie has a better chance of doing so if a different character is the villain.
