My wife and I were blown away! Without question, this is the highest quality CGI we've ever seen. The characters and settings all looked fantastic. The various kinds of magic were incredibly beautiful. The girls were incredibly cute. I grew up loving books, but increasingly enjoying movies and video games. It is a delight when these bring sights I could not have imagined - and this movie is a great example. Places and characters weird and wonderful, of multiple genres.
Another reviewer felt the writers really love tragedy. This begs two responses. First, this tale wasn't written for this movie. White Snake is a Chinese legend, at least hundreds of years old. This is an adaptation, and the writers took creative license, but the basic story is already set - like any telling of King Arthur, Aladdin, etc. Second, watch the ending more closely, and think about it. This is not actually a tragedy. There is also a post credit scene, which ends the movie quite delightfully.
In short, a fun treat for all sorts of audiences. Especially those who like Chinese legends. But more beautifully brought to screen than any animated film I've seen before. This raised the bar. I can't wait for more!
