One of the big things to remember is that ST is basically a bunch of vignettes using the same setting. Other than the main characters and some ongoing elements (Klingons, Romulans, etc) one episode of ST was basically unto itself.
SW OTOH was basically one big storyline almost entirely focused around a specific bloodline. More than a few think SW is very nearly a case of throwing Dune and LOTR in a blender and adding some cutting edge special effects. Not that there's anything wrong with that per se, SW is some entertaining fare to be sure, but IMO SW is good not because of some great story but in the onscreen telling. For instance, at least IMHO, if you were to put SW in a book I'd put it behind Dune and well behind Tolkein's work. (I put LOTR ahead of SW onscreen too but that sort of thing is almost blonde's vs brunettes...some people just have preferences)
