So, can someone explain the divergent ratings?

Generally speaking, when you look at the current IMDb ratings for this short film, you get:

Young males hate this film.
Young females love it.
As you look at each older age group, ratings tend to converge around 5-6.

There aren't enough votes to be statistically significant, particularly given that the sample isn't random, but still that just strikes me as bizarre.

Discuss.

(I'm not a young male, but I hated it and gave it a 2.)
