I remembering reviewing this film when it was released in theaters. I was in a good mood, and there were aspects of the film that(at the time) I preferred over The Lion, The Witch, And The Wardrobe. I rated the film an 8 out of 10, which was essentially stating that it was a "great film". I was wrong.
Why? Well, for many reasons. The new Prince Caspian film has some serious problems, one of the most prominent being the failure to establish a sense of danger and dread. Consider the fact that the very first scene in the original Chronicles of Narnia dropped us right into the middle of a bombing run. People were dying, and if the Pevensie family didn't move fast, they were going to die too. What better a way to establish conflict? Intense scenes like those helped make up for the film's obvious visual misinterpretations of the story in terms of the action.
In contrast, Prince Caspian does not have any bombing runs or crashing waterfalls. Just more of the same, kid-friendly conflict. Only this time, it was cheesier. To tell the truth, I don't think the first film ever really established that the Pevensie kids were really capable of the majority of the violence they inflict in the Prince Caspian film, and that's only part of the problem.
I would again submit that the creators' kid-friendly approach to the action is very unrepresentative of C.S. Lewis' stories. Sure, his books weren't explicit in terms of violence in a sense. But Lewis does mention that it takes place. Having said that, I find the complete and utter lack of true violence simply castrating in terms of the story, not to mention silly and unbelievable. The Chronicles Of Narnia should not be treated with any less authenticity than the Lord Of The Rings series.
