This is actually a Hollywood movie, as its producing team were mainly made up from Hollywood. So it is a mature commercial movie, rather than a Mainland product. The production, including the direction, the story, the performance, the visual effect, etc, are all better than those of an average Mainland one. And since it was released at the summer vocation, it was not strange to see its box office has won the first place for all the Chinese movies up till now.
The characterization of Huba, the leading baby monster, is very cute.
