1. Man of Steel was met with mixed reviews. You either love it or hate it. The sequel should fix its problems. There needs to be more character development. We need to see Clark Kent.
2. Batman needs his own film first. In this World's Finest film, you need to introduce Jim Gordon, Alfred, Robin, and the rest of Batman's supporting characters.
3. This is too soon for a Batman film. People complained with The Amazing Spider-Man, saying it was only 5 years after Spider-Man 3. Those same people are now praising this decision to make World's Finest, which is a Batman reboot/Man of Steel sequel. By this film's release, it will have only been 3 years since the disappointing conclusion to Nolan's Dark Knight Trilogy. That is disrespectful to Nolan, after all he did to save the Batman franchise.
4. We need other DC movies, besides Batman and Superman. Where are the Flash and Wonder Woman films everyone wants? In fact, where is the much anticipated Justice League film?
These points prove that DC fails at movies. I am still excited for this film. I am just worried. Until DC does something right,make mine Marvel!
