Short answer
Everything that is out of this world.
Longer answer
I love to see all the imagination of the alter reality. I would say something like Cyberpunk. 
However, all magic and unicorn are also welcome. 
The alter reality lies within the connection to our knowledge or in other word, the perception of what reality is to me.
Most of my day spends on dreaming of another way of living. 
Not that I don't like my life. But fantasy world is sooo tempting.
So when it comes to any forms of art. I want to see what artists think of.
They may suggest an alter reality or depict what they have seen from our social.
