Really, most of the Star Wars EU is far too comic book-ish for me, visually and developmentally speaking, and tends towards absurd extremes and caricatures. The only books I enjoyed I enjoyed as if they were exceptionally good fanfictions, and usually were enjoyable because of some stupid running gag throughout the novel- Wedge Antilles dressed up as an Ewok in his cockpit, astromech droids modified to serve what was basically beer, etc.
Then, later on, the franchise got infected with the trendy bits of sci-fi: organically 'grown' ships and whatnot. Nevermind that the right metals and ceramics are easier to use, stronger, less reactive and so on.
Really, I love the movies, even those with Jar Jar, but I can't stand maybe 80% to 90% of the SW-EU. You'd be right to call the movies' plot and characters simplistic and generalized in many ways, but I've got to say that I prefer the timelessness and myth of the trilogies to the constant and minutely detailed comic book feel of the EU.
