New and original themes. Now THAT'S what we all love about Hollywood.
Kidding aside, the epic novel turned movie will probably do well--looks like a popcorn flick in every sense. A lot of action, ridiculous looking special effects, a big-time actor that'll be able to carry the movie no problem, and likely some cheesy dialogue in which the audience won't have to think too hard. There have been worse things made. This won't be life-changing, but it'll likely be pretty entertaining.
