I got the impression that the filmmakers were motivated a bit more by Fantasy Filmmaking Cliches 101 (with a lot of help from the pattern set by LOTR) than by a deep understanding of what Lewis was writing about.
I think that you're definately right on that point. What we've been seeing in recent years is Hollywood grasping to somehow recreate the success of
The Lord of the Rings and resulting in a string of pale immitators in much the same way that they flooded the market with crappy sci-fi & monster movies in the late 1970s/early 1980s trying to cash in on the popularity of
Star Wars &
Jaws. (Although, I suspect the Christian aspects of
The Chronicles of Narnia would have been obscured even further had
The Passion of the Christ not made such a crapload of money.)
I think some of the "liberal media" conspiracy theories don't entirely hold water. True,
Prince Caspian didn't do as well as
Harry Potter. However, it grossed twice as much domestically as the allegedly anti-Christian
The Golden Compass.
My opinions, for the record...
I think the
Harry Potter movies are a lot of harmless fun. They're full of great acting and some compelling stories. But I'm not as obsessed as some people.
The Lord of the Rings is one of the greatest epics ever committed to film and will still be so 50 years from now.
The Golden Compass was crap. The acting was crap. The FX were crap. The ending was non-existent. The underlying ideas are suspect at best. Frankly, I suspect that the whole idea of your soul as a talking animal walking beside you works a lot better in a book. When you actually see it, it just looks silly.
I was completely unimpressed with
The Lion, the Witch, & the Wardrobe. Neither the characters nor the acting really grabbed me. Theologically, it focuses on the part of Christianity--Jesus as a sacrificial death to transfer the punishment of my sins onto him--that I have the most difficult time with.
Prince Caspian was somewhat better. The action was more exciting. The acting still wasn't very good. (The best actor in the whole thing was the dwarf.) The theology was less prominent but still a bit dubious to me. I may be interpreting this the wrong way but it seemed that the movie was trying to criticize Peter's sins of pride. To me, it looked more like Peter was just trying to be pro-active rather than laying about waiting for Aslan/signs-from-above to give him instructions. I took his behavior more as one of those the-Lord-helps-those-who-help-themselves kinda things, which the movie seemed to disagree with.
But, ultimately, I think that
Prince Caspian's greatest sin was nothing more than coming out in a crowded May, sandwiched between
Iron Man and
Indiana Jones & the Kingdom of the Crystal Skull.
