Disney's first and the second were great it was not easy to make the sequel successful. Disney gave up and the 20th century fox tried just as hard as it could at least it seemed to me like that. It just anyway made it level with the first two episodes and it became great trilogy I enjoyed. I expect the 4th series but the key actor already too much grown to act in Narnia, because he already grown up adult in a new movie as I have seen. The dragon boy!
It is touching that those all series has a rising up slowly to the victory. First one and the second one has slow pace with a bit longer playtime, however this third one choose a bit fast pace and seems to have a bit faster tempo.
Very good feature of this movies are the casts reflection of real world growth as they are growing in the same time parallel in this world. They are living as we do and they are aged like us. So it is afraid not to see the 4th, but who knows the upcoming future?
In short great sequel, Thanksgiving to 20th century fox.
