I liked this review of 9 from thedartmouth.com
"Computer graphics have become a staple of modern cinema. Few movies are released without CGI, and many recent computer-animated films — such as “Wall-E” (2008) and “Up” (2009) — are favorites of our generation.
As a fan of this expanding medium, I find it disappointing that computer animation is never featured in action and horror movies. For this reason, it was a thrill to watch “9,” which finally introduces the computer-animation genre to a more mature audience.
“9” is an absolutely gorgeous film full of suspense, and the animation makes it possible for the creators to include sequences that would be impractical with live action."
