Take a quick guess. How many of the twenty highest grossing films of the decade were original properties, neither sequels, remakes, nor based on material from another medium (as they say)?
Check the answer here.
Now a lot of this is unfair, of course. Pirates of the Caribbean is derivative in name only. And there's not necessarily anything wrong with derivative movies. LOTR was pretty good. But really.
Out of the top 50 grossing films of this decade, there are only 9 movies based on original properties. And five of those nine films were created by Pixar Animation Studios.
If you're curious, the two non-Pixar, non-Dreamworks-animation original films in the top fifty are:
The Day after Tomorrow
Have a nice decade.
