>But according to the graph, Toy Story 3 was the least polarizing movie of 2010 and that seems like a prime example of a movie "safely" manufactured for an existing fanbase.

I think this is likely due to that fact that Toy Story 3 was superior to Toy Story 2, leaving people pleasantly surprised.

(It is actually unexpectedly complex. The first scene features the toys calmly discussing and preparing for their own deaths. It's quite stark.)
