I thought about this when all the rave reviews were rolling in for the expansion. I wouldn't complain about "deceptive marketing", but I certainly felt like my expectations weren't met. I'm glad I'm not completely alone here, though it's clearly a minority.

Once the story got going, I didn't expect us to be the villains, but I did keep expecting the story to "get dark" (i.e. bad stuff happening to us), and that seemed in quite short supply. I was disappointed that no one important died. I was disappointed that we never had to "harness the darkness" (whatever that could mean). I was disappointed that the light sickness amounted to little more than a couple of sneezes. I was disappointed that the light sickness was cured without us actually intending to fix it, and the excuse was that Arbert kissed your boo-boos better. Bleh.

That ending was so sickly sweet with its "everything's fine and dandy" that it really ended on a sour note for me.
