I saw it last wednesday!!! I liked Narnja, but I do not think that it is better than Harry Potter 4.
Narnja is, in my opinion, very cute and nice story for kids and adults. It has got a lot of very nice effects and the "animals" are made better than I had expected (in the trailer it seems as if there would be too many "animal"-conversations).
Some things while the battle on the field remebered a lot to the battle scenes of the "Lord of the Rings"!
In the end, it was nice to see, but not better than Harry Potter. Harry Potter is just great to see and to read. *voldemort*
