Obviously you've not bothered to read any of it. Or you'd be aware of titles like:

Agent of the Empire which is set very shortly before ANH and is about a James Bondesque Imperial spy.

Dark Times which is set between the two trilogies and lives up to its title.

Tales which was a compilation of various short stories of all kinds. From comedy to tragedy it explored every facet of the Star Wars galaxy.

Or even Knights of the Old Republic which dealt with a Jedi apprentice who was framed for the murder of his classmates by his masters.

Heck even the stuff that does deal with the Jedi vs. Sith conflict is excellently done as can be seen in Legacy. So before you try to tear something down why don't you try having some basic knowledge about the subject first.
