So I took the kids to Prince Caspian today on a whim. All in all a very good movie... unless you wanted to see the plot of C. S. Lewis' novel Prince Caspian in movie form. I mean, they didn't change the entire story: the characters generally have the same names, for example.
I was generally impressed with the movie adaptation of The Lion, the Witch, and the Wardrobe, which led me to actually see Prince Caspian in the theatre, rather than waiting for the DVD release. Even The Lion, the Witch, and the Wardrobe was not completely true to the novel, but it was as close as Disney can reasonably be expected to get, so I tolerated the minor plot deviations, and very much enjoyed the movie.
But Prince Caspian took so many liberties, it went beyond "liberty" into "anarchy". They inserted at least one major battle, gutted Trumpkin's role, didn't even name most of the major Narnian characters, ignored Dr. Cornelius' long relationship with Caspian (briefly alluded to it, but also indicated it was substantially different than in the novel), totally changed Aslan's return (neither Bacchus nor Gwendolyn are even mentioned), and developed an entirely weird romantic interest.
All was not lost: the movie is really very well made, and the story is not bad, just... er... novel. The actors were very good, the battle scenes epic, the score very good, and the filming well done. All in all, it was a good movie, and I shall certainly buy the DVD on release. I did enjoy it, if not so much as Spiderwick earlier this year. Of course, I haven't read Spiderwick, which could have a lot to do with that.
