Welcome to (Space) Fantasy Island

This episode is a little spacey. 

But is it space opera, space fantasy, space western, or just space between the ears of The Guys where intelligent life should be?  Is it science fiction, science fantasy, or some subgenre of a subgenre?  It’s yet another ed-Jay-cation opportunity where Robbie and Art shed some light (or throw some shade?) on the differences between all the novels and movies and TV shows Jay might have time to watch if he retires soon.  (Neither is likely.)
