The thing that should not be
I agree that its not the greatest live demos, its not easy playing on live TV though, its not as easy as it looks, throw in the fact that you have to host the show, do pre-prep with the producers and probably only have an hour or two to play the game before the show then shes not doing such a bad job. Also the other presenter also struggled a bit when he previewed batman and hes a gaming veteran.
I am a gaming veteran dude Trust me its not that hard, I been playing games for 16 years. They just really terrible its like they do it half hearted.
