So earlier I posted about the Skill Shot shot system in Bulletstorm and how I felt it was lacking in terms of being the focus of the game.
 
But now there's this:

 As I said before, I felt like the demo was really short and might not have given a good sense of gameplay.   Maybe PCF/Epic felt that the gameplay was so strong it would stand on its own in its barest form, or that they did not want to give anything away, but it had the opposite of the intended effect on me.  
I feel like RPS got to play a completely different game than I had in the demo, one with incredible set-pieces and varied gameplay.  Then I think back on the dry repetition in the demo and then I reach for the Advil because I can't reconcile the two things in my head. I really want to play the game described in the article, but yet that does not seem to be the game I actually got to play.
 
So I have a few question to toss out there. Feel free to answer more generally too, especially about what impact demos and previews have on your opinions of games.

Did you play the demo and did it change your impressions of the game for better or for worse?
 
Does the hands-on I posted above improve your opinion of the game,  especially if the demo it changed it for the worse?
 
Given my feelings and the feelings of a lot of the people who have posted here and elsewhere, do you think releasing the demo as it was designed was a mistake? Would PCF/Epic been better off revealing a more juicy slice of gameplay or would that  have been too much of a "spoiler"?
 
And finally, would you trust a preview enough to revise your opinion in the face of what might have been a disappointing first-hand experience based on the demo?
