IGN:
The epic Cloud Atlas is unconventional, defying what we're used to seeing in a studio film. It's complex, weaving varied stories from multiple eras together and linking them with theme and intent. And it's ballsy; this film should get credit right off the bat for at least trying something new. Cloud Atlas is not very successful though as it reaches high and falls just a bit short.
"defying what we're used to seeing in a studio film"
Cloud Atlas is an independent film. Distributed, but not in any way made, by Warner Bros. It was financed entirely by third party financiers outside of Hollywood.
Perhaps he should do some research next time?
