While I agree with a few of your points, I still feel like Torment served a couple of really useful roles, in this regard.
For the snobs, it provided some dumbed-down entertainment that wasn't TOO dumb. I mean, at least they were trying something different and meaningful, even if you don't feel like they pulled it off particularly well.
Second, for the people with limited exposure to good literature or philosophy -- it provided a glimpse at some ideas they might not have seen before, even if it WAS through Matrix-colored glasses.
Every snob starts somewhere, y'know?
