I did spend the afternoon viewing THE CHRONICLES OF NARNIA: PRINCE CASPIAN on Blu-ray. As a film, it features the same kind of intense battle scenes as the first NARNIA adventure (different adversaries, of course), so while I find the characters appealing, it didn't seem much different than the first one. (Perhaps that's why its US box-office take was about half of what the first one made; it was much more popular overseas.)
The Blu-ray does look spectacular, however, as good or better than the last one, and the DTS-HD Master Audio offers 7.1 channels, so the sound is REALLY enveloping. Very impressive production.
