If you are looking for nitpicking, you will be satisfied, if you just want to have a good time, you will be as well. Don't just take it seriously and take the film's message for what it is. It is not a film meant to be perfect, but an entertainment, and in that area it delivers better than most blockbusters and family movies I have seen these last years.
If I had something to say, it would be, stop this amount of not so great CGI and either increase the quality of the final product or use less of it.
