Grammar-School levels of soft science in Science Fiction roleplays.

I get more fed up with sci-fi RPs that lack a coherent style than sci-fi that's soft with humanoid aliens.  If there's a Galaxy where lizard people and humanoid aliens are in a Cold War and cosnsitent with the mentality it is going for, I'd be fine with it.  

It's when nothing has any coherency/focus or you get the try-hards who focus on "realistic sci-fi" only to proceed to make laughably cliched aliens that I start losing interest.  Than again I get bothered by people who seem more concerned on the technical details on some fictional spaceship than like, a story.

I can't tell you how many NRPs I lost interest in because of that one faction which rubbed me the wrong way that was allowed to exist.  It's just too many.
