Peter Ericson’s review published on Letterboxd :
This film is darker and more complex than "The Chronicles of Narnia: The Lion, the Witch and the Wardrobe". The single combat between Peter and Miraz is pulse-raising; the big battle ends in a way that is expectedly convenient but quite effective. There are also scenes reminiscent of "The Lord of the Rings". The four principal cast members have grown into their roles and exude more confidence than they did in the previous installment. Tilda Swinton’s brief appearance as the White Witch is threatening and sinister; Miraz is not as interesting a villain as the White Witch. With a few exceptions, "The Chronicles of Narnia: Prince Caspian" is better than the previous film in the series.
(At the screening I attended, there was a guy who whispered almost every line to his child. I simply cannot understand people taking their children to a subtitled film and then whispering the text to them.)
