The reason, Bertoni says, is that “Napoleon Dynamite” is very weird and very polarizing. It contains a lot of arch, ironic humor, including a famously kooky dance performed by the titular teenage character to help his hapless friend win a student-council election. It’s the type of quirky entertainment that tends to be either loved or despised. The movie has been rated more than two million times in the Netflix database, and the ratings are disproportionately one or five stars.

Mathematically speaking, “Napoleon Dynamite” is a very significant problem for the Netflix Prize.

I draw a matlab graph for this "Napoleon Dynamite" base on my 3 prediction files, it did is a polarizing movie. ha ha, amazing.By the way, in "qualificaiton.txt" file, we have 10551 prediction entries of "Napoleon Dynamite" need to be guessed. In other words, we have 10551 weird behavior kids need to be controlled well, Wow..
If we can’t understand our own preferences, can computers really be any better at it?

Matlab Command
plot(Small_x,svdMix3151(1:100),'g-o',Small_x,userAVG3151(1:100),'r-x',Small_x,movie3151AVG(1:100),'k:');
