This was actually kind of fun. It very much is a reference ridden kids' movie, yet it does hold your attention with an engaging, albeit thin story, and some incredible animation.
The film does often hint at a deeper emotional core that never truly comes to fruition. It's as if they had to remove the exploration of the themes in order to make place for all the extra easter eggs.
Nonetheless I had fun with it. Even if it might not stand the test of time.
