Ya know, they should have continued certain origional stories instead puking out licensed-based ones each year with a LEGO Star Wars set each year. I got really annoyed when Lego released "LEGO BEN 10 ALIEN FORCE" sets that only mentioned the aliens. Where's the goddamn BENMOBILE!? I really hate Ben 10 because of the "oh my aliens are superior so I'm not gonna talk about other things other than how great my powers are with these guys" bullshit.
Exo-Force DID had a couple of nice sets, even though the story was bland and they never finished the never-ending battle between the drones and the humans.
At least they expanded the LEGO World stories.
NOTE: Used to be a LEGO Bionicle collector before I got ahold of my first minifigs.
