In short it is brilliant.

There were some parts that really stand out as different than the rest that I didnt care for while in the cinema, but afterwards I really liked them and what they did for the movie (even if it did make a big mess out of explaining how/what was going on!)

It is one of those films for the whole families that I genuinely think was created for the 20-40 year olds with their own kids. I highly doubt the sequel will come even close but who cares, the first is a masterpiece of film.
