The problems with the new Star Wars movies cannot be summed up easily, but let's give it a shot . . .
The characters are completely flat and blah. They have no charisma, and the acting is horrible. In some of the "love story" parts you could practically tell that they were just reciting lines off a page. I don't know who did the casting, but what were they smoking when they cast those two for Anakin and Amidala??? The actor playing Anakin is so annoying, and he looks sooooo wimpy. In Episode IV when Darth walks into the space ship at the beginning he's huge, almost towering over everyone else. I'm hoping Episode III can explain this.
The new movies are such a departure from the mood and feel of the originals. The old ones focused on characters and development of the story, whereas the new ones are completely focused on battles and special effects. Anyway, the point is that nothing can compare to the zaniness of the first three. The story was well done, and the characters were memorable. Who can forget Han Solo, Luke, Leia, or Chewbacca? . . . but do you really think anyone is going to care when Amidala ends up a corpse in Episode III?
