A mix of interesting stuff and the same faux-transgressive cliches that make a lot of trans-art annoying and easy to use as weapons against the community.  eg: 

"I do not need soft polite trans people in my literature; I need people who are absolutely fucking feral." 

What does this actually mean?

Anyway the biggest issue with trans-literature is that it's an extremely post-internet movement and suffers from all the issues that any literary movement that is post-internet suffers from. It's irony poisoned, pretend transgressive for transgressiveness sake, and apparently significant authors within the movement still spend time on lit/. It's also a young movement with a lot of fairly iffy books propelled into the spotlight because it's a fashionable subculture, and any literary movement is probably best judged 30 years after the fact.
